coupling is the manner and degree of interdependence between software modules.

cohesion is the degree to which the elements of a module belong together.

In a good software design, it is always desirable to have less interaction among modules( Low coupling ) and high cohesion ( advantages: 1: Reduced module complexity 2: Increased system maintainability 3:  Increased module reusability )

(B) High cohesion and low coupling

(Ideal software design requires less interaction between modules so that any module can be easily modified/replaced as the requirements change)
