Match List - I with List - II.

List – I (Software design principles)	List – II (Definition)
A.	Cohesion	I.	Degree to which one module relies on another module.
B.	Coupling	II.	Dividing a software system into distinct modules.
C.	Abstraction	III.	Degree to which elements of a module belong together.
D.	Modularity	IV.	Simplifying complex reality by modeling classes appropriate to the problem.

Choose the correct answer from the options given below:

Correct option is C

A. Cohesion (III: Degree to which elements of a module belong together)
· Cohesion refers to how closely related and focused the responsibilities of a single module are. It’s a measure of the strength of relationship between elements within a module, which matches Definition III.
B. Coupling (I: Degree to which one module relies on another module)
· Coupling indicates the level of dependency between modules. High coupling means modules are highly dependent on each other, while low coupling means they are more independent. This aligns with Definition I.
C. Abstraction (IV: Simplifying complex reality by modeling classes appropriate to the problem)
· Abstraction is a design principle that focuses on hiding complex details and showing only the necessary aspects of an object, which allows a simpler view of the reality being modeled. This matches Definition IV.
D. Modularity (II: Dividing a software system into distinct modules)
· Modularity is the practice of dividing a software system into separate components or modules that can be developed, tested, and maintained independently. This aligns with Definition II.
