Show answer & explanation
Correct answer: C
Correct matching:
Coupling: Reliance of a code module upon other code modules.
Cohesion: Focus of a code/module upon a single goal.
Scalable: Easy to add functionality to software without having to redesign it.
Readable: Easy to visually inspect the design of the software and understand its purpose.
Final matchings:
I → Reliance of a code module upon other code modules (Coupling).
II → Focus of a code upon a single goal (Cohesion).
III → Easy to add functionality without redesign (Scalable).
IV → Easy to visually inspect and understand purpose (Readable).
Why these are correct:
Coupling: High coupling means strong dependencies between modules, so coupling refers to reliance on other modules.
Cohesion: High cohesion means a module does one clear task, so it reflects focus on a single goal.
Scalable: A scalable design allows functionality or capacity to be increased without major redesign.
Readable: Readability makes it easy for developers to inspect code/design and understand its purpose quickly.
