Question:
What is the relationship between Cohesion and Coupling?
What is the relationship between Cohesion and Coupling?
Show Hint
A tightly focused module needs fewer outside links, so watch what happens to coupling.
Updated On: Jul 2, 2026
- High cohesion often leads to low coupling
- High cohesion often leads to high coupling
- Low cohesion often leads to low coupling
- Cohesion and coupling are unrelated concepts

The Correct Option is A
Solution and Explanation
Step 1: Cohesion measures how strongly the parts inside one module belong together. Coupling measures how much one module depends on others.
Step 2: Good design aims for high cohesion and low coupling.
Step 3: When a module is highly cohesive it keeps all related work inside itself, so it needs fewer connections to outside modules. Fewer external dependencies means lower coupling.
Step 4: Therefore high cohesion tends to produce low coupling. They are related and move in opposite directions in a well-designed system.
So the answer is option A.
