When analyzing the options provided in relation to object-oriented programming (OOP), encapsulation is specifically the feature that can be implemented to restrict access to certain components of an object. Here’s an overview of each term in this context:

1. Encapsulation: This is the concept of wrapping data (attributes) and the methods (functions) that operate on the data into a single unit or class. It allows the internal state of an object to be hidden from the outside, exposing only what is necessary through public methods (also known as getter and setter methods). This helps in maintaining the integrity of the data.

2. Polymorphism: This feature allows methods to do different things based on the object it is acting upon, often using method overriding or method overloading. While technically linked to encapsulation, it does not define it.

3. Inheritance: This is the mechanism by which one class can inherit attributes and methods from another class. Inheritance promotes code reusability but is not encapsulation.

4. Abstraction: This refers to the concept of hiding the complex reality while exposing only the necessary parts. It is related to encapsulation but focuses on the external interface rather than the internal workings.

Final Answer

The feature that can be implemented using encapsulation is Encapsulation itself.
