The correct option is (D). If the final kinetic energy is less than the initial kinetic energy, then some of the original kinetic energy is converted into internal energy of the final particles. These reactions are energy absorbing (endoergic) and are analogous to the collisions we have been calling “inelastic”. Therefore option (B) is ruled out. For elastic collisions, in which the kinetic energy does not change, we must have initial total kinetic energy is equal to the final total kinetic energy. In practice this means that the identities of the colliding bodies do not change and that there are no inertial regroupings of their constituents. Therefore option (C) is ruled out
