Answer 2

If the sum of all the forces acting on a body is zero, then the body may be in equilibrium provided the forces are maybe in equilibrium provided that forces are concurrent. (option A)

1. It is not necessary that the body will be in equilibrium if all the forces acting on the body is 0.
2. Two equal and opposite forces have their line of action at a certain distance apart act of a body. In this case, it was rotational motion rather than translational motion due to torque produced. Hence not in equilibrium.
3. But the torque is 0 if the forces are concurrent. This will eliminate both translational and rotational motion.
