Right choice is (a) True

To explain: The moments in the 2D can be added algebraically just like the scalar quantities. But the need is that the signs must be taken into consideration. As if clockwise is positive, so anti clockwise is negative. And the result can be negative too. That is a counter clockwise direction.
