How can the composition (black diamond) relationship be used to relate Requirements?

AComposition allows requirements to inherit properties and requirements relationships

BComposition allows role names to be assigned to sub-requirements thus providing a contextual reference

CComposition allows a particularly useful requirement to be reused by multiple higher level requirements or specifications

DComposition allows a requirement to be decomposed into sub-requirements as long as they don't add to or change the meaning of the original requirement.

Given a system for keeping birds away from airports One component, described by the following diagram directs audio signals at birds that approach a runway, its parts, as part properties, are typed by blocks.

A systems engineer has identified some blacks that type the pan properties, but as the design becomes more specific, the engineer discovers that these blocks exist in multiple variants.

What modeling choice does the engineer face at this point?

Awhether to model part properties as (a) a library, or (b) a logical hierarchy

Bwhether to model part properties as (a) a library or (b) a hierarchy of non-composite relationships

Cwhether to model variants of blocks that type part properties as (a) explicit subclasses of the blocks, or (b) part-specific types.

Dwhether to model variants of blocks that type part properties as (a) implicit subclasses of the blocks, or (b) part-specific types
