The feature of Object-Oriented Programming (OOP) that reduces the use of nested classes is a) Inheritance.

Inheritance allows a class to inherit the properties and methods of another class. This means that instead of creating nested classes (a class within a class), you can create a new class that inherits the properties and methods of the existing class. This makes the code more readable and manageable.

Here's a step-by-step explanation:

1. In OOP, a class is a blueprint for creating objects. It defines a set of properties and methods that are common to all objects of that class.

2. A nested class is a class defined within another class. It's a way of organizing code, but it can make the code more complex and harder to read.

3. Inheritance is a feature of OOP that allows a class to inherit the properties and methods of another class. The class that is inherited from is called the superclass, and the class that inherits is called the subclass.

4. When a subclass inherits from a superclass, it gets all the properties and methods of the superclass. It can also add new properties and methods or override the ones it inherited.

5. This means that instead of creating nested classes, you can create a subclass that inherits the properties and methods of the superclass. This reduces the need for nested classes, making the code more readable and manageable.
