Correct answer
B. The controller.
Explanation
In the photo you can see a tram driver in the cab who is operating the master controller on the control desk with one hand. To change the driving speed, you use the master controller - answer B.
The master controller is a lever or a control handle that the tram driver uses to control the force of acceleration and braking, and so the speed of the tram. The reverser (answer A) is used to set the direction of travel - forwards, backwards or in the neutral position. The adjuster (answer C) is a bar for moving the switch blade of the points by hand. The names are similar, so it is worth learning them well. Use the master controller smoothly, without sudden movements, so that you do not jerk the tram and put passengers at risk of falling.
