Question

Quizplus · Accepted Answer

After about 100,000 years, the internal temperature of a nebular disk can reach 1 million degrees due to various processes such as accretion, gravitational collapse, and fusion reactions. This high temperature is necessary for the creation of protostars and eventually, nuclear fusion and the formation of a main sequence star. Therefore, option D is the most accurate choice.
