How does the spectrum of a distant star reveal the star's chemical composition? Choose one: A. The total energy of light received from a star, as determined by its spectrum, is directly related to its chemical composition. B. The type of light that is being produced the most within the spectrum of a star is directly related to its chemical composition. C. Dark lines, also called absorption lines, within the spectra are "fingerprints" for the different atoms and molecules within a star's atmosphere. D. The chemical composition of a star determines how bright the star appears to be and, in turn, how much of the spectrum is received
