The correct answer is (b) 461N

Easy explanation: The couple is simplified by taking the direction of the rotation of the body as positive or negative. That is if the clockwise direction is positive then the anti-clockwise direction is taken as negative. After this the forces are a determined and are added vetorially to get the resultant force.
