Statement I: If a sphere of mass `m`moving with speed `u` undergoes a perfectly elastic head-on collision with another sphere of heavier mass `M` at rest (`M gt m`), then direction of velocity of sphere of mass `m` is reversed due to collision (no external force acts on system of two spheres).
Statement II: During a collision of spheres of unequal masses, the heavier mass exerts more force on the lighter mass in comparison to the force which lighter mass exerts on the heavier one,

Options

A. statement`-1` is True, Statement `-2` is True, Statement `-2` is a correct explanation for Statement `-1`.
B. Statement `-1` is True, Statement`-2` is True, Statement`-2` is NOT a correct explanation for Statement `-1`
