Question

Quizplus · Accepted Answer

The process described in the sentence is ionization, which is the stripping of electrons from atoms, and this results in the emission of light or radiation. Therefore, the best choice is A, where the star ionizes the hydrogen gas and makes it glow. Choices B and C are incorrect because they do not describe the process described in the sentence. Neutralization is the opposite of ionization and would not result in the emission of light, while swallowing the star is not a process that could happen in this context.
