Answer: Option A

Solution(By Examveda Team)

The process by which excess energy is lost is Fluorescence.
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence.
Fluorescence occurs when an excited molecule, atom, or nanostructure, relaxes to a lower energy state (usually the ground state) through the emission of a photon without a change in electron spin.
