(A) Round Robin
(B) First-In First-Out

Explanation: Round Robin – Preemption takes place when the time quantum expires
First In First Out – No Preemption, the process once started completes before the other process takes over
Multi Level Queue Scheduling – Preemption takes place when a process of higher priority arrives
Multi Level Queue Scheduling with Feedback – Preemption takes a place when process of higher priority arrives or when the quantum of high priority queue expires and we need to move the process to low priority queue
