D
All of the above
E
None of the above
Correct Answer: Round-robin
Round-robin is the preemptive process scheduling algorithm. Each process is provided a fix time to execute, it is called a quantum. Once a process is executed for a given time period, it is preempted and other process executes for a given time period.
