Explanation

CPU scheduling algorithms determine the order in which processes are executed. Here's a brief description of each option:

• FCFS: Executes processes in the order they arrive. No consideration of burst time. Time complexity can lead to longer average waiting time.
• SJF: Selects the process with the shortest CPU burst time next. This minimizes average waiting time.
• Round Robin: Processes are executed in a cyclic order with a fixed time quantum. Burst time is not directly considered.
• Priority Scheduling: Chooses the process with the highest priority, which may or may not be related to burst time.

Correct Answer: B. SJF (Shortest Job First)
