Solution

The correct option is C
both current and magnetic field direction is reversed simultaneously.

The direction of rotation of a motor can be reversed by changing the direction of current or by changing the direction of the magnetic field. The direction of rotation of a motor remains unchanged if both current and magnetic field direction is reversed simultaneously.
