A. Single level implementation

B. Two level implementation

C. Multi level implementation

D. None

Answer: Option B

Solution(By Examveda Team)

Two level implementation is used in operating system to separate mechanism from policy. It uses two different schedulers, one lower-level scheduler which can only select among those processes in memory to run. That scheduler could be a Round-robin scheduler. The other scheduler is the higher-level scheduler whose only concern is to swap in and swap out processes from memory.
