The correct answer is: B. a parent class.
Inheritance is a mechanism in object-oriented programming where a class acquires the properties and methods of another class. The class that is inherited from is called the parent class, and the class that inherits is called the child class.
For example, if we have a class called Animal, and we want to create a new class called Dog, we can inherit from Animal. This means that Dog will have all the properties and methods of Animal, plus any additional properties and methods that we define for Dog.
Inheritance is a powerful tool that can be used to reduce code duplication and make code more reusable. It
can also be used to model real-world relationships between objects.Here is a brief explanation of each option:
- A. an object. An object is an instance of a class. It is a concrete representation of a class.
- C. a variable. A variable is a storage location that can hold a value. It is not a class.
- D. a function. A function is a block of code that can be called from another part of the program. It is not a class.
