(b) : Photon is the massless and chargeless stable particle which moves with the velocity of light. Energy of photon, $E=h v$ where $h$ is Planck's constant and $v$ is frequency of photon. It's momentum is given by, $p=\frac{E}{c}=\frac{h v}{c}$ In a photon-electron collision both total energy and total momentum are conserved.
