Answer is Right!
Answer is Wrong!
The correct answer is 2 minutes.
The G marker gate signal is a type of railway signal that is used to indicate whether or not a train is allowed to proceed through a level crossing. When the signal is at ON, it means that the level crossing is clear and the train may proceed. However, the train must stop for at least 1 minute by day and 2 minutes by night before proceeding. This is to allow time for any pedestrians or vehicles that may be crossing the tracks to clear the area.
The other options are incorrect because they do not represent the correct amount of time that a train must stop before proceeding through a level crossing when the G marker gate signal is at ON.
