Correct answer: D
A destructor is a special member function that is automatically invoked when an object goes out of scope or is explicitly destroyed using delete. When a class creates objects dynamically (using new), it is mandatory to provide a destructor to release the dynamically allocated memory. If memory is not released properly, it may lead to memory leaks.
