In a chain drive, how do chain pitch and sprocket teeth count influence torque capacity?

• A. Torque capacity increases with larger sprockets (more teeth) and smaller chain pitch; higher tooth count on driven sprocket increases torque capacity for a given chain.
• B. Torque capacity decreases with larger sprockets.
• C. Torque capacity is independent of sprocket size.
• D. Larger chain pitch increases torque capacity.
