The correct answer is A. T/369(3b).
T/369(3b) is a train order that authorizes a train to pass an advanced starter that is defective. The order must be issued by the stationmaster (SM) and must include the private number of the same station.
T/369(2B) is a train order that authorizes a train to pass an advanced starter that is working. The order must be issued by the SM and must include the private number of the next station.
T/369(4b) is a train order that authorizes a train to pass an advanced starter that is working and has a speed restriction. The order must be issued by the SM and must include the private number of the next station, the speed restriction, and the reason for the restriction.
T/369(5b) is a train order that authorizes a train to pass an advanced starter that is working and has a speed restriction and is also approaching a siding. The order must be issued by the SM and must include the private number of the next station, the speed restriction, the reason for the restriction, and the location of the siding.
In this case, the advanced starter is defective and IBS is working. Therefore, the SM must issue T/369(3b) authority with private number of same station to pass the advanced starter.
