Cool, I was right :P
MasterMath:
I actually think there is a drag force .. but yeah D is the most reasonable one :P

The answer is C.
The moments about a point is the force times he perpendicular distance.
Use trigonometry to find the length d.
Then you simply times this by 2N, to get the moments.
Then what you have to do is add the moments on the other side is also anti-clockwise.
