This is College Physics Answers with Shaun Dychko. An inelastic collision means that some of the kinetic energy is lost in the system and it's probably turned into heat which becomes external to the system. Momentum is conserved because it doesn't -- there are no external net forces acting on the system. So B is the answer.
