Face ID will attempt to recognize your face three times before asking for your passcode. This is to prevent unauthorized access to your device by someone who looks similar to you or has a photo of you. If Face ID fails to match your face after three attempts, you can either enter your passcode or swipe up from the bottom of the screen to try Face ID again. You can also adjust the settings for Face ID to make it more or less sensitive to variations in your appearance, such as wearing glasses, a hat, or a mask.Reference:Use Face ID on your iPhone or iPad Pro - Apple Support,iOS 12: How to retry Face ID after a failed attempt - 9to5Mac

To start up in safe mode on a Mac with Apple silicon, you need to follow these steps1:

Shut down your Mac, then press and hold the power button for three seconds.

When the startup options window appears, select your startup disk.

Click the Continue in Safe Mode button.

Log in to your Mac.

Safe mode can help you identify whether issues you're experiencing are caused by software that loads as your Mac starts up.It prevents your Mac from loading certain items, performs a First Aid check on your startup disk, and deletes some caches1.You can verify that your Mac started up in safe mode by using the System Information app1.

The other options are incorrect because they either do not show the Continue in Safe Mode button, or they do not use the correct key combination or timing to enter safe mode.

Disk Utility on Mac supports several file system formats for formatting, partitioning, and erasing disks.According to the Apple Device Support Reference Materials1, these formats are:

Apple File System (APFS): The file system used by macOS 10.13 or later, which features strong encryption, space sharing, snapshots, fast directory sizing, and improved file system fundamentals. APFS is optimized for the Flash/SSD storage used in recent Mac computers, but it can also be used with older systems with traditional hard disk drives (HDD) and external, direct-attached storage. APFS supports four variants: APFS, APFS (Encrypted), APFS (Case-sensitive), and APFS (Case-sensitive, Encrypted).

Mac OS Extended: The file system used by macOS 10.12 or earlier, which is also known as HFS Plus or HFS+. Mac OS Extended supports journaling, which helps protect the integrity of the file system in case of power outages or hardware failures. Mac OS Extended also supports four variants: Mac OS Extended (Journaled), Mac OS Extended (Journaled, Encrypted), Mac OS Extended (Case-sensitive, Journaled), and Mac OS Extended (Case-sensitive, Journaled, Encrypted).

ExFAT: A file system that is compatible with both Mac and Windows computers, and can be used for transferring files between them. ExFAT supports larger file sizes than FAT32, up to 16 EB, and larger volumes, up to 128 PB. ExFAT does not support journaling, encryption, or case sensitivity.

MS-DOS (FAT): A file system that is compatible with both Mac and Windows computers, and can be used for transferring files between them. MS-DOS (FAT) supports two variants: FAT16 and FAT32. FAT16 is limited to 2 GB volumes and 4 GB files, while FAT32 can support up to 2 TB volumes and 4 GB files. MS-DOS (FAT) does not support journaling, encryption, or case sensitivity.

Therefore, the correct answer is A, C, D, and F.

Two-factor authentication is an extra layer of security for your Apple ID, designed to make sure that you're the only one who can access your account---even if someone else knows your password1.When you sign in with your Apple ID for the first time on a new device or on the web, you need both your password and the six-digit verification code that's automatically displayed on your trusted devices1.A trusted device is a device that you've already signed in to with your Apple ID and that can receive verification codes1.You can also add or remove trusted devices and phone numbers from your Apple ID account page1. Two features of two-factor authentication for a personal Apple ID are:

It ensures that only the account's owner can access the account.This is because you need to verify your identity with both your password and a verification code that is sent to a device or phone number that only you have access to1.This prevents unauthorized access to your account even if your password is compromised or stolen1.

It can be accessed on trusted devices.This means that you can sign in to your Apple ID account on devices that you've already verified with two-factor authentication without needing to enter a verification code again1.This makes it easier and faster to access your account on devices that you use frequently and trust1.

According to the image you sent, the screen sharing service is disabled because the remote management service is turned on. You can't have both screen sharing and remote management on at the same time. Remote management allows you to perform more advanced tasks on another Mac, such as installing and configuring apps, helping remote users, and creating detailed reports. Screen sharing allows you to view and control another Mac's screen. To enable screen sharing, you need to turn off remote management first. You can do this by going to System Settings > General > Sharing and deselecting Remote Management. Then you can check the box next to Screen Sharing to turn it on. Alternatively, you can use Apple Remote Desktop, a commercial app that combines the features of screen sharing and remote management, and works with both Intel-based and Apple silicon Macs.Reference:Turn Mac screen sharing on or off - Apple Support,Mac screen sharing won't work?
