Quizplus · Accepted Answer

During the initial phases of a supernova explosion, the luminosity of the star increases dramatically. In fact, it can increase by a factor of up to 10⁸ compared to its pre-supernova luminosity. This increase in luminosity is due to the enormous amount of energy released by the explosion, which can briefly outshine an entire galaxy. Therefore, option A) is the best choice.
