The correct answer is: B. full pitch
A full-pitch coil is a coil in which the two coil sides forming the coil are spaced exactly one pole pitch apart. This means that the two coil sides are aligned with the poles of the stator. Full-pitch coils are the most common type of coil used in electric motors.
A short-pitch coil is a coil in which the two coil sides forming the coil are spaced less than one pole pitch apart. This means that the two coil sides are not aligned with the poles of the stator. Short-pitch coils are used in some electric motors to reduce the amount of noise generated by the motor.
Neither of the above is not a correct answer.
