In an clastic collision of two billiard balls. there is deformation in shape of balls momentarily. During the collision potential energy increases due to deformation of balls and kinetic energy decreases. Hence, total energy remains constant but kinetic energy is not conserved.
Law of conservation of energy always applies, in every case.
Thus, both Assertion and Reason are false.
