This allows for the abstraction and protection of data within the object, making it inaccessible to the outside world without appropriate methods to access and modify it. Option A, converting objects into data streams, is incorrect as it refers to the process of serialization, which is a way of converting an object into a data format that can be stored or transmitted over a network. Option C, inheritance of properties, is incorrect as it refers to the process of a child class inheriting the properties and methods of its parent class. Option D, separation of program code into different files, is incorrect as it refers to the concept of modularity and organizing code into different files for better code maintenance. Encapsulation, on the other hand, is about
