In a core-collapse supernova, detectors on Earth may observe neutrinos before the brightest visible light from the explosion. Which explanation best connects energy transfer, particles, and waves?
A
Neutrinos arrive first because they travel faster than light in vacuum.
B
The collapse releases energy in multiple forms; neutrinos escape dense matter more readily, while photons can scatter many times before visible light emerges.
C
Visible light is delayed because photons have no energy until they reach Earth.
D
The explosion is chemical combustion, so no nuclear or gravitational energy is involved.
