Which analogy best describes inheritance in programming?

• A. Inheritance is the concept of objects acquiring properties from parent objects.
• B. Inheritance is a database technique.
• C. Inheritance is a form of encryption.
• D. Inheritance is copying files.

Answer: (A)

Inheritance in programming is like a child class receiving features from a parent class. The main idea is that the child automatically gains the parent’s data and behaviors, which you can reuse as is or refine. This lets you build new classes without rewriting common code, and you can customize or extend how those inherited parts work. Objects of the child can often be treated as objects of the parent, enabling flexible and interchangeable use through polymorphism.

This isn’t about how data is stored in a database, nor about securing data with encryption, nor simply duplicating files. Those ideas describe different concepts, while inheritance specifically captures the way a class derives properties and methods from another class.
