Hint: In collision of the two bodies, the kinetic energy between them stays constant. What we can see is that there is not a single form that kinetic energy is converted into on a net basis.
Complete step by step solution:
A collision between two bodies that is elastic occurs when their combined kinetic energy stays constant. There is no net conversion of kinetic energy into other forms, such as heat, noise, or potential energy, in an ideal, fully elastic collision. The only thing that stays constant at this point in a collision is momentum because a collision generates some heat, changing temperatures as well as kinetic energy. Any impact maintains momentum. Only in elastic collisions does Kinetic energy remain constant. Momentum is constant during a collision, but kinetic energy and temperature might not.
Hence option B is the correct answer.
Note: A collision occurs when two moving bodies come into contact and receive a sudden force during their motion. Both bodies exert some force on one another during the collision. Collision force is the name given to this force. Both bodies change their momentum and energy as a result of the impact. Both the law of conservation of energy and the law of conservation of momentum can be used to calculate the velocities in a collision.
