Consider the following scenario. A process has generated a page fault, and the Operating System is about to run the working set algorithm with T-7ms to select a page to replace. The current virtual time of the faulting process is 20ms, and the following table gives details for the process's pages currently in memory: Page Time of last use (ms) 1 2 3 4 5 15 6 18 5 11 M Select one or more: ☐a. The time of last use of page 2 is set to 20 b. Page 4 is selected to be removed ☐c. Page 5 is selected to be removed d. Page 1 is not in the working set 0 1 1 0 1 R 0 1 0 1 0 Select all the correct statements about the execution of the working set algorithm on these pages. Assume that the algorithm examines pages in the order they are listed in the table (from 1 to 5). Consider the following scenario.
