Answer: B

Explanation:

Abstractions in a model are helpful because they can express or suppress detail as needed. This capability is essential in managing complexity in a model by focusing on the high-level, essential aspects of the system while omitting or simplifying the less critical details. This selective detail management aids in understanding and analyzing the system’s core functionality without getting overwhelmed by its intricacies. Abstractions facilitate clearer communication, more focused analysis, and more efficient system design by highlighting the most relevant aspects of the system in various contexts.
