____ is a qualitative measure of the consistency of functions within a single class.Question 17Select one:a.​Cohesionb.​Encapsulationc.​Couplingd.​Visibility

The correct answer to the question is:

1. Cohesion

Cohesion refers to the degree to which the elements of a module or class belong together. A class with high cohesion has elements that are closely related in functionality, which enhances maintainability and reliability. This is opposed to coupling, which measures how dependent a class is on other classes.

2. Encapsulation

Encapsulation is about restricting access to certain details of an object and exposing only what is necessary, thereby bundling the data together with the methods that operate on that data.

3. Coupling

Coupling indicates the degree of interdependence between different modules or classes. Low coupling is generally preferred as it indicates that classes can operate independently.

4. Visibility

Visibility usually refers to the accessibility of class members (attributes and methods) in object-oriented programming, guiding which parts of the code can access certain functionalities.

In summary, the term that accurately describes a qualitative measure of the consistency of functions within a single class is cohesion.
