Torque requires positions and directions from diagram Steps:

• Identify radius r = diameter/2 = 0.4 m / 2 = 0.2 m.
• Torque for each force: τ = F × r × sinθ, where θ is angle between position vector and force.
• Parallel forces imply same direction, but points of application and θ are unspecified without diagram.
• Not enough information to compute exact sinθ or moment arms for net torque.

Why D is correct:

• Not enough information.

Why the others are wrong:

• A: Not enough information.
• B: Not enough information.
• C: Not enough information.

Final answer: Not enough information.
