Correct answer: C
Correct answer: Short-Term Scheduler
The short-term scheduler is also called the CPU scheduler. It chooses one process from the ready queue and allocates the CPU to it.
Switching vs allocating: the scheduler makes the selection/allocation decision; the dispatcher performs the actual context-switch mechanics. Among the scheduler options, the short-term scheduler is the one involved in CPU switching among ready processes.
