The correct answer is: D. the page is not found in the memory.
A page fault occurs when a process attempts to access a page of memory that is not currently in physical memory. The operating system must then find a page to swap out to make room for the requested page, and then load the requested page into memory.
A deadlock occurs when two or more processes are waiting for each other to release a resource that they are currently holding. This can cause a system to become unresponsive or even crash.
Segmentation is a memory management technique that divides memory into segments. Each segment can be used for a different purpose, such as code, data, or stack.
