A multiphase system involves multiple stages or phases of service, which is exactly what is happening in this scenario with three different counter stops. The other options are not as applicable. M/M/1, M/M/S, and M/D/1 refer to specific queuing models that involve only one or two stages of service, and M/M/1 with finite population assumes there is a limit to the number of customers in the system, which may not be the case in a busy DMV.
