(A) Ratio of final kinetic energy of particle C to particle A after collision is 2
(B) Ratio of kinetic energy of particle B to A after second collision is greater than 1
(C) Relative velocity of A w.r.t B after second collision is v/4
(D) Percentage change in kinetic energy of A after all collisions is nearly 76 percent
