Answer:
C. half rotation
Explanation:
In an electric motor, the change in the direction of current in the coil depend on the number of the pole we used in the motor. The more pole we will use the less number of rotation to change the direction of the current.
As we are talking here about a simple electric motor, so will consider here only two-pole, one south and one north. So, in every half rotation, the coil of the motor will change its pole so the current will also change it's direction according to pole.
