Quizplus · Accepted Answer

According to our present theory of solar system formation, the solar nebula was primarily composed of hydrogen and helium gas, followed by hydrogen compounds (such as water, methane, and ammonia), and finally rock and metals. Therefore, option C lists the major nebular ingredients in the correct order of abundance, starting with the most abundant. Option A is incorrect because it lists hydrogen compounds first, which are less abundant than hydrogen and helium gas. Option B is incorrect because it places rock before hydrogen compounds. Option D is incorrect because it only lists a few specific hydrogen compounds without including the abundant hydrogen and helium gases.
