The given system has a service time that is normally distributed, which implies that it follows a General Distribution (G) rather than a Deterministic (D) distribution. Also, since there is only one bay and arrival rate is not specified, we cannot assume Poisson arrivals, and therefore, it is not an M/M/1 or an M/D/1 model. Hence, the best choice is M/G/1.
