light behaves primarily as a particle when it
travels from one place to another.
interacts with matter.
both of these
neither of these

Explanation:

To determine when light behaves as a particle, we recall the wave - particle duality of light. When light travels from one place to another, it shows wave - like behavior (e.g., diffraction, interference). However, when light interacts with matter (such as in the photoelectric effect, where photons (particles of light) eject electrons from a material), it behaves as a particle. So light behaves as a particle when it interacts with matter.

Answer:

B. interacts with matter
