Quizplus · Accepted Answer

FCFS algorithm works on the principle of first-in, first-out, which means the task that arrives first is served first. This can be easily achieved by using a FIFO (First-In-First-Out) queue, making it a simple algorithm to implement. Therefore, option A is the best choice.
