Best answer
Right option is (b) Particle nature of light

Best explanation: The wave theory of light could not explain the laws of photoelectric emission. It was only by particle nature of light that Einstein was able to explain the photoelectric emission.

It was considered that when a photon of incident radiation collides with an electron, it transfers its energy to the electron, thus causing photoelectric emission.
