Which of the following statements describes what will happen when both the polarity of the field poles, and the direction of current to the brushes of a DC motor are reversed?

Correct Answer: Option B — The direction of rotation of the armature will remain the same.

Reversing both the field pole polarity and the armature brush current simultaneously results in two opposing magnetic reversals that cancel each other out. Consequently, the net electromagnetic torque vector remains unchanged, and the armature rotation direction continues exactly as before.
