Answer:
The correct answer is option A. "Line spectra".
Explanation:
Line spectra is a method that is used to determine the temperature of a star. Line spectra is based on the principle that, depending on the temperature of a star, a line is traced which is compared to the continuum temperature that could either generate a emission (hotter) or absorption (colder) line. A spectrum of lines depending on the temperature have been established under the code OBAFGKM, where O is the hottest an M is coldest.
