Correct Answer

Explanation

Correct Answer Explanation:

Multitasking is possible because the OS uses time-sharing — the CPU switches rapidly between tasks, giving each a small slice of time. This happens so fast that all tasks appear to run simultaneously.

Why the other options are incorrect:

  • Option B: Only one CPU cycle handles just one operation — that alone doesn't enable multitasking.
  • Option C: Fixed memory doesn't enable multitasking; memory management does.
  • Option D: Batch mode processes jobs one after another — the opposite of multitasking.
