Best answer
Right choice is (c) Both Reversing and Non-reversing

Best explanation: Dynamic braking is employed to brake both reversing drives and non-reversing drives.

In dynamic braking, the electrical energy generated during stopping action is released as heat through a voltage regulated transistor and resistor.
