a. First come first serve basis. b. Shortest Job first c. Round vobin d. Priority
The answer is b. If a process with shorter burst-time is present in the queue, the CPU has to execute that particular process before moving on to other processes with larger Burst time. This may create a problem for processes with larger Burst time because a new process might come up when these processes are just about to go inside the Running State.
Option d might seem a possible answer but Processes with same priorities are executed on a First-come first-serve basis which might solve the problem of starvation. Also, we can use Multi-level Feedback queues to solve the problem of Priority Scheduling.
Note: Burst-Time is the actual time a Process requires to finish execution.
