Answer:

C. as electrons jump from higher energy levels to lower levels

Explanation:

Atoms of elements are capable of emitting photons i.e. light energy. They, however, only do so when they become excited at first. They remain excited for a short while and then begin to move from their excited electron level to a lower level.

As they move from high electron level to low electron level, atoms emit light energy in form of visible, ultraviolet light in a process called SPONTANEOUS EMISSION. Therefore, according to this question, atoms emit visible and ultraviolet light as electrons jump from higher energy levels to lower levels.
