The correct options are
B E = mc2
C interference
D diffraction
According to planck's quantum theory the energy emitted or absorbed by a body is not continuous but it is discontinuous in the form of a small discrete particles called quanta or photon. It is directly proportional to frequency of light. E = hv.
E = mc2
It is an equation by Albert Einstein showing that energy and mass are interchangeable. It's not related to wave and particle nature of photon. Light is a transverse electromagnetic wave. Diffraction and interference are phenomena observed with all waves. So, it's not related to wave and particle nature of photon. So, only E = hv related to wave and particle nature of photon.
