Which brakes are used to soft stop the tram at the tram stop?

This question is about the brakes used when stopping a tram at a stop. For a gentle stop, the electrodynamic brake is used, and in the final stage the parking brake - the answer is B.

The electrodynamic brake uses the traction motors working as generators, so it brakes smoothly and without wearing the linings. At very low speed it loses its effectiveness, so just before stopping, the mechanical parking brake comes on; it stops the tram and holds it in place during the stop. All brakes at once (answer A) means emergency braking, and the track brake (answer C) is an emergency brake and is not used in a normal stop. Smooth braking protects standing passengers from falling.
