Show the correct answer
Correct answer
B. Persons in the cabin.
Explanation
In the photo we see the tram driver's cab, seen from the control desk, with a view of snow-covered tracks and a junction; there are interior mirrors in the cab. A person in the cab may reduce the tram driver's field of view - the answer is B.
A person in the cab may cover the windscreen or a mirror, so the tram driver will not notice a danger at the side of the tram. Rain and snow (answer A) limit visibility, but they are not the only such factor. The ergonomics of the seat (answer C) affect comfort and the use of the controls, and when the seat is well adjusted, it does not reduce the field of view. While driving, nobody should stand in the cab in a way that blocks the view.
