Ans. 
Inheritance is a concept in object-oriented programming where a class can inherit attributes and methods from another class.

• Derived class (subclass) inherits properties and behaviors from a base class (superclass)

• Can have multiple levels of inheritance, creating a hierarchy of classes

• Example: Animal class can be a base class with Dog and Cat
