The "delete" operator in C++ releases a block of bytes that was previously allocated using the "new" operator. This is used to prevent memory leaks and free up memory that is no longer needed. Options A, C, and D are not valid operators in C++. The delete operator in C++ is used to release a block of memory that was allocated previously using new operator. This memory can then be reused for other purposes. The free() function is used in C language for this purpose, but in C++, delete operator is a better choice because it automatically calls the destructor of the object being deleted. The return keyword is used to return a value from a function, and dealloc is not a valid operator in C++.
