Show answer and explanation

Correct answer: (c) Like both of wave and particle

Explanation

Light behaves both as a wave and as a particle (wave–particle duality).

Interference, diffraction and polarisation show its wave nature, while the photoelectric effect shows that it comes in packets of energy called photons.
