What modeling choice does the engineer face at this point?

Choose the correct answer.

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?
A . whether to model part properties as (a) a library, or (b) a logical hierarchy
B. whether to model part properties as (a) a library or (b) a hierarchy of non-composite relationships
C. whether to model variants of blocks that type part properties as (a) explicit subclasses of the blocks, or (b) part-specific types.
D. whether to model variants of blocks that type part properties as (a) implicit subclasses of the blocks, or (b) part-specific types
