  • In the following question, a statement of Assertion is followed by a statement of Reason. Mark the correct choice. Assertion: In an elastic collision of two billiard balls are in contact with each other. During the short time of collision, kinetic energy is conserved. Reason: Energy, spent against friction does not follow the law of conservation of energy

    A
    Both assertion and reason are true and reason explains assertion correctly.
    B
    Both assertion and reason are true but reason does not explain assertion correctly
    C
    Assertion is true but reason is false
    D
    Assertion is false but reason is also false
