Answer: (iv) Dispatcher

Clarification: Short-term scheduler selects the process; Dispatcher gives control (context switch, switch to user mode, jump to instruction). Many textbooks loosely say Short-term scheduler, but most precise is Dispatcher. If Options force choice between schedulers only, answer (i) Short Term Scheduler. Here dispatcher is listed, so (iv) is most accurate.
