Correct choices:
- Light is absorbed, which produces characteristic lines.
- Lines are dark on a visible light background.
- Lines are produced by electrons being excited.
Explanation: Absorption spectra occur when atoms in a cooler gas absorb specific wavelengths from a continuous source, exciting electrons to higher energy levels; the missing wavelengths appear as dark lines against the bright continuum. Emission (bright lines on a dark background) and electrons returning to lower levels describe emission spectra, not absorption.
