    Correct Option - 2


    Detailed Solution:

    (A) If c  is the velocity of light

    so,   E = h ν   (Energy of photon)

    (B) Velocity of photon is equal to velocity of light i.e. c.

    (C)  λ = h p

    p = h λ

    p = h v c

    (D) In photon-electron collision both total energy and total momentum are conserved.
