Explanation:

- Option 1: The kinetic energy remains conserved, but not the momentum.

- This is incorrect. Momentum is always conserved in collisions (inelastic or elastic) if no external forces act, but kinetic energy is not conserved in an inelastic collision.

- Option 2: The momentum remains conserved, but not the kinetic energy.

- This is the correct answer. In an inelastic collision, the total momentum of the system stays the same, but some kinetic energy is converted to other forms like heat or deformation.

- Option 3: Both the kinetic energy and the momentum remain conserved.

- This describes an elastic collision, not an inelastic one.

- Option 4: Neither the kinetic energy nor the momentum remains conserved.

- This is not true. Momentum must always be conserved in collisions (assuming no external force).
