How is the light emitted by an atom related to its electron configuration?

Question

A Light is produced when an electron moves from a higher to a lower energy level. The color of the light (as we see it) depends on the amount of energy emitted by the electron.
B Light is produced when an electron moves from a lower to a higher energy level. The color of the light (as we see it) depends on the amount of energy emitted by the electron.
C Light is produced when a proton moves from a higher to a lower energy level. The color of the light (as we see it) depends on the amount of energy emitted by the electron.
D Light is produced when a proton moves from a lower to a higher energy level. The color of the light (as we see it) depends on the amount of energy emitted by the electron.
