The correct answer is C. The split phase motor has two windings on the stator.
A split phase AC induction motor runs on a single phase and splits the phase into two windings, a run winding, and a start winding, on the stator. The start winding axes is 90 degrees electrically to the run winding. This helps to produce a rotating magnetic field at startup and gets the motor spinning. This secondary 'start' winding on the stator is a key feature of split phase motors.
