In elastic collision, both the kinetic energy and momentum are conserved. Conservation means that both the kinetic energy and momentum will have the same values before and after elastic collision.

As the object A has low mass than object B. Hence upon collision, object B moves forward, while object A will move backward. So option "C" is correct.
