• A. To reduce noise, parasitic torque and starting torque, but increases pullout torque
• B. To reduce noise parasitic torque, starting torque and pullout torque
• C. To reduce noise and pullout torque, but increases parasitic torque and starting torque
• D. To reduce parasitic torque and starting torque, but increases starting torque and pullout torque
