Options
8 N-m in C.W.D.
8N-m in A.C.W.D.
6 N-m in C.W.D.
6 N-m in A.C.W.D.

Solution
8 N-m in C.W.D
Explanation:
The moment of a couple equals one force multiplied by the perpendicular distance between the forces: $$20\text{N} \times 0.40\text{m} = 8\text{N-m}$$. The forces in the diagram produce a clockwise turn.
