Q. If $c$ is the velocity of light in free space, the correct statements about photon among the following are : A. The energy of a photon is $E=hv$. B. The velocity of a photon is $c$. C. The momentum of a photon, $p=\frac{hv}{c}$. D. In a photon-electron collision, both total energy and total momentum are conserved. E. Photon possesses positive charge. Choose the correct answer from the options given below:
A) A, C and D only
B) A, B, D and E only
C) A and B only
D) A, B, C and D only
