A) 5.0 N.m.
B) 7.0 N.m.
C) 9.0 N.m.
D) 12 N.m.
E) 20 N.m.

To calculate torque, we use the formula T = rF, where T is torque, r is the distance from the point of rotation to where the force is applied, and F is the force applied. In this case, r = 30.0 cm = 0.3 m and F = 40 N. Therefore, T = 0.3 m x 40 N = 12 NF1F1F1S1F1F1F10m. So the correct choice is D.
