Quizplus · Accepted Answer

A waiting line system has three main components: arrival or inputs, queue discipline or the waiting line itself, and the service facility. Therefore, option D is the best choice.

Option C mentions three concepts related to queuing, but not the three main parts of the system. Option E mentions some factors that can affect queuing, but doesn't encompass all the parts of the system.
