The sort options that are available in stories are ascending and descending order, and multiple dimensions together. Ascending and descending order allow you to sort data by one or more dimensions or measures in ascending or descending order. Multiple dimensions together allow you to sort data by more than one dimension in a hierarchical order. Dimensions and measures together, and multiple measures together are not valid sort options in stories. Verified Reference: [SAP Analytics Cloud - Sorting]

The design options that are available when you create a new story are optimized and classic. Optimized design option allows users to create stories using an intuitive and simplified interface, with fewer options and more automation. Classic design option allows users to create stories using a full-featured and flexible interface, with more options and more control. CSS and style are not design options when you create a new story; they are concepts related to web development and formatting. Verified Reference: [SAP Analytics Cloud - Story Design Options]

A section is a way to group and organize widgets in a story based on a dimension. To create a section, you need to have the following:

A dimension that you want to use as the basis for grouping the widgets. You can choose any dimension from any model in the story.

One or more widgets that you want to display in each section. You can add any type of widget, such as charts, tables, geo maps, etc.

You can create sections in both the Classic Design Experience and the Optimized Design Experience, but the process is slightly different. Therefore, the correct answer isdimensionandwidget, as they are required to configure a section in a story

Unbooked is the term that refers to dimension members with no numeric data values associated with them. For example, if a dimension has members A, B, C, and D, and only A and B have numeric values in a measure column, then C and D are unbooked members. Booked, transformed, and exception aggregation are not terms that describe dimension members. Verified Reference: [SAP Analytics Cloud - Unbooked Data]

The correct answers are B. Public and D. Embedded.These are two of the dataset types that SAP Analytics Cloud supports, according to the SAP Help Portal1.A public dataset is a standalone dataset that is stored in SAP Analytics Cloud and can be found in a folder location on the Files page1.An embedded dataset is a dataset that is saved within a story and does not appear in the Files list1.You can convert an embedded dataset to a public one if you want others to be able to use it1.

The other options,

A) Import and C. Live, are not dataset types, but data source types.You can import data from a file or other data source to create a dataset or a model2.You can also use live data from a source system to create a model, but not a dataset2.
