Solution

The correct option is A Paging

Technique to implement virtual memory where memory is divided into units of fixed size memory is Paging.

The most common way of allocating memory to processes in modern operating systems is a type of non-contiguous allocation called paging. The logical address space of every process is divided into fixed-size (e.g., 4KB) chunks called pages.

Memory paging is a memory management technique for controlling how a computer or virtual machine's (VM's) memory resources are shared. A computer can address memory beyond the amount physically installed on the system. ... The portion of the hard disk that acts as physical memory is called a page file.

Virtual memory is a memory management capability of an OS that uses hardware and software to allow a computer to compensate for physical memory shortages by temporarily transferring data from random access memory (RAM) to disk storage.
