A. All of these

NON PREEMPTIVE SCHEDULING 

• • In this, once the resources (CPU cycle have been allocated to a process, the process holds it until it completes its burst time or switches to the 'wait'state.
  • A process can't be interrupted until it terminates itself or its time is over.
  • If a process that has a long burst time is running the CPU, then the process that has less CPU burst time would starve.
