What combines wrapping data and methods within classes and implementation hiding?

Inheritance
Polymorphism
Encapsulation
Abstract Classes

The correct answer is: Encapsulation

Encapsulation is the correct answer because it combines the concepts of data and methods within classes and also hides the implementation details from other parts of the code. Inheritance (A) may involve data and methods within classes but does not necessarily involve implementation hiding. Polymorphism (B) is a way of making code more flexible but does not necessarily involve wrapping data and methods within classes. Abstract Classes (D) may include data and methods within classes but do not necessarily hide implementation details. Therefore, the correct answer is C.
