Correct answer: A
The correct answer is Option 1: Virtual Memory.
Virtual Memory is a memory management technique that creates an illusion for users and applications that the computer has a very large, contiguous main memory. It allows the system to address secondary memory (like an HDD or SSD) as if it were part of the main memory (RAM).
This is achieved by mapping "virtual addresses" used by a program into "physical addresses" in computer memory. When the RAM is full, the operating system moves inactive data to a space on the secondary storage (often called a page file or swap partition), bringing it back only when needed.
