A light particle moving horizontally with a speed 12 m/s strikes a very heavy block moving in the same direction at 10 m/s. The collision is one dimensional and elastic.  In elastic collision, the conservation of momentum and conservation of kinetic energy are valid. After the collision, the particle will
(a)	move at 12 m/s opposite to its original direction	(b)	move at 8 m/s in its original direction
(c)	move at 8 m/s opposite to its original direction	(d)	move at 12 m/s in its original direction
