What does a destructor do in C++?

Destroys the class definition
Frees memory allocated during the program execution
Ensures cleanup is performed when an object is no longer in use
Resets all class member to zero

The correct answer is: Ensures cleanup is performed when an object is no longer in use

A This option is incorrect because a destructor does not destroy the class definition, it frees up any resources or memory associated with an object of that class. B: This option is incorrect because a destructor does not necessarily free up any memory during program execution, it is only responsible for tidying up any resources allocated for the object. D: This option is incorrect because a destructor does not reset class members to zero, it only handles the cleanup and deallocation of resources for the object.
