Elastic And Inelastic Collisions

In an inelastic collision, the total momentum of the system is conserved, but the kinetic energy is not conserved. Some of the kinetic energy is converted into other forms of energy, such as heat, sound, or deformation. This is in contrast to an elastic collision, where both momentum and kinetic energy are conserved.
Therefore, the correct statement is that in inelastic collisions, momentum is conserved but kinetic energy is not.

The correct option is (B) : In inelastic collisions, momentum is conserved and kinetic energy is not conserved.
