Answer: Light moves in a straight path.
Reason: Particle models explain straight-line travel (rays) and sharp shadows. The other choices — spreading through an opening and diffraction at a barrier — are classic wave behaviors, and production by changing electric/magnetic fields comes from Maxwell's electromagnetic wave theory. (Modern physics: light has both particle and wave properties — photons exhibit particle-like straight‑line propagation in many situations but also show interference/diffraction.)
