Option B Locality of reference is applicable to the process
A page fault occurs when a program attempts to access a block of memory that is not stored in the physical memory, or RAM. The fault notifies the OS that it must locate the data in virtual memory, then transfer it from the storage device, such as an HDD or SDD, to the system RAM.
We can reduce page faults using some methods
1. We can increase size of main memory
2.Decreasing the degree of multiprogramming
3.Locality of reference is applicable to the process
4.Possible to increase the page size.
