A. Move constructor

Detailed Explanation

Answer: (A) Move constructor

A move constructor is used to transfer resources from another object that is usually a temporary or expiring object.

Its typical form is:

ClassName(ClassName&& other);

The && represents an rvalue reference.

Move construction can avoid unnecessary copying of resources such as dynamically allocated memory and can therefore improve performance in modern C++.
