Answer 2

ANSWER:

The correct option is a) balance each other.

EXPLANATION:

     A couple consists of two forces acting opposite to each but not at the same point, so as to produce a torque which makes the object rotate. The net force applied by a couple is zero as the forces are equal and opposite. When two couples are present whose moments are equal and opposite then the forces are already balanced.

    As for the torque, it is also balanced as the moments are opposite to each other and both couples try to rotate the object in opposite directions with same strength. So they balance each other and the correct option is a).
