Show answer & explanation
Correct answer: A
Matching the functionalities of process components:
A → III: Medium-Term Scheduler handles swapping (moving suspended processes to secondary storage).
B → IV: Long-Term Scheduler loads processes from disk into main memory (Ready queue).
C → I: Short-Term Scheduler selects which process from the Ready queue moves to the Running state.
D → II: Dispatcher assigns the CPU control to the selected process.
Thus, the correct mapping is A-III, B-IV, C-I, D-II. The correct option is A.
