Which statement about class unique_ptr (of the new C++ standard) and dynamic memory allocation is false?
A) An object of class unique_ptr maintains a pointer to dynamically allocated memory.
B) When a unique_ptr object destructor is called (for example, when a unique_ptr object goes out of scope), it performs a destroy operation on its pointer data member.
C) Class template unique_ptr provides overloaded operators * and - so that a unique_ptr object can be used just as a regular pointer variable is.
D) Class unique_ptr is part of the new C++ standard and it replaces the deprecated auto_ptr class.

The destructor of a `unique_ptr` does not perform a "destroy operation" on its pointer data member; instead, it deletes the dynamically allocated memory that the pointer points to, effectively calling the destructor of the managed object and releasing the memory.
