What concept allows a C++ class to ensure internal consistency by controlling modifications to its data?

Encapsulation
Inheritance
Polymorphism
Template

The correct answer is: Encapsulation

Encapsulation is the concept that allows a C++ class to ensure internal consistency by controlling modifications to its data. This means that the class can restrict access to certain parts of its data and control how it is modified, ensuring that it maintains its integrity. Inheritance and polymorphism are important concepts in object-oriented programming, but they do not specifically address the issue of controlling modifications to data within a class. Templates are useful for creating generic classes, but they do not pertain to data modification control within a class.
