The correct answer is:

a. Degree to which components of a module are interrelated ✅

Explanation:

• Cohesion measures how closely related and focused the responsibilities of a single module are.

• High cohesion means that the elements within a module (like functions and data) are highly related and work together toward a single purpose — which is a good practice in software design.

• Low cohesion means the module does too many unrelated things — making it harder to understand, maintain, and reuse.

Other Options:

• b. Performance of the system — Not directly related to cohesion.

• c. Ease of testing modules — Cohesion can help testing, but this is not the definition.

• d. Independence between modules — That refers to coupling, not cohesion.

✅ Final Answer: a. Degree to which components of a module are interrelated

The correct answer is:

c. Interdependence between software modules ✅

Explanation:

• Coupling refers to the degree of interdependence between software modules.

• Low coupling is desirable because it means modules can function independently, making the system easier to maintain and modify.

• High coupling means modules are highly dependent on each other, which can lead to more complex and fragile software.

Other Options:

• a. Flow of data within the system — This is related more to data flow or cohesion, not coupling.

• b. User interface quality — Not related to coupling.

• d. Database schema — Deals with data structure, not module interdependence.

✅ Final Answer: c. Interdependence between software modules
