Show answer & explanation
Correct answer: C
A page fault is a hardware interrupt triggered when a running program references a virtual memory page that is not currently loaded into the physical main memory (RAM). The operating system must then fetch the required page from secondary storage (hard disk/SSD).
Thus, a page fault occurs when the page is not in main memory. Correct option is C.
