The correct answer is: B. Station
A train guard is a railway employee who is responsible for the safety of passengers and crew on a train. They are typically stationed at a train station, where they can monitor the train’s progress and ensure that it is safe to depart.
A point is a railway switch that is used to direct the movement of trains. It is typically located at a junction, where two or more tracks meet.
A break van is a type of railway carriage that is used to carry railway brakes. It is typically located at the end of a train, where it can help to slow the train down in an emergency.
Any place is not a safe place to present the train guard. The train guard must be presented at a station, where they can monitor the train’s progress and ensure that it is safe to depart.
