Answer: (a).A data structure that lists physical pages in use in a process's address space Explanation:A working set is a per-process data structure that lists the current physical pages that are in use in the process’s address space. It helps the system determine each process’s active use of physical memory and which memory pages have not been accessed in a while, so that those pages can be paged out to disk and removed from the process’s working set.
