The correct answer is: D. Capacitor run motor.
A capacitor run motor is a type of single-phase induction motor that uses a capacitor to improve the power factor of the motor. The capacitor provides a leading current that helps to offset the lagging current of the motor, resulting in a higher power factor.
A shaped pole motor is a type of single-phase induction motor that uses a shaped pole winding to improve the power factor of the motor. The shaped pole winding creates a more uniform magnetic field, which results in a lower current draw and a higher power factor.
A split phase motor is a type of single-phase induction motor that uses two windings to create a rotating magnetic field. The two windings are out of phase with each other, which creates a torque that causes the motor to rotate. Split phase motors typically have a power factor of around 0.65.
A capacitor start motor is a type of single-phase induction motor that uses a capacitor to improve the starting torque of the motor. The capacitor provides a leading current that helps to offset the lagging current of the motor, resulting in a higher starting torque. Capacitor start motors typically have a power factor of around 0.75.
In conclusion, the capacitor run motor is the only type of motor listed that will operate at a high power factor.
