Show answer & explanation
Correct answer: A
The working set model is explicitly based on the principle of locality. This principle states that as a process executes, it moves from one locality (a set of pages that are actively used together) to another. By tracking and keeping the active pages (the working set) of a process in main memory, the operating system effectively minimizes page faults and prevents thrashing.
Thus, the correct option is A.
