Correct answer
A. With less force so as to prevent further locking of the wheels.
Explanation
The question is about braking after getting the tram out of a skid. You should brake with less force so as to prevent the wheels from locking again - answer A.
A skid during braking happens when the braking force is greater than the grip of the wheels on the rails allows. After you have controlled it, you brake more gently, using the sander if necessary, because the same conditions can easily cause another skid. Releasing the dead man's device (answer B) activates emergency braking, which on slippery rails is not a way to brake in a controlled manner. Reverse-current braking (countercurrent) after setting the reverser to reverse (answer C) is not allowed and may damage the motors.
