Inheritance in programming allows which of the following?

• A. In the child class, nothing from the parent can be used.
• B. Inheritance prevents code reuse.
• C. The child class inherits features from the parent and can override or extend them.
• D. Inheritance automatically optimizes performance.

Answer: (C)

Inheritance lets a child class automatically use the methods and data defined in its parent, so you can reuse existing code instead of rewriting it. The real power is that the child can tailor that inherited behavior by overriding methods to change how something works, and can also add new features of its own. For example, a base class Vehicle might have a move method; a Car subclass can reuse that move method but override it to reflect acceleration behavior, and also introduce new functionality like honk or checkFuel. Inheritance enables code reuse and customization; it doesn’t prevent reuse. It also doesn’t automatically improve performance—any speed or efficiency gains come from the specific implementation, not the inheritance mechanism.
