Quizplus · Accepted Answer

Giant molecular clouds are predominantly composed of hydrogen gas, with small amounts of other elements such as carbon and oxygen, as well as dust particles. While carbon monoxide is commonly used to trace the presence of molecular gas in such clouds, it is not the most abundant material. Water vapor is also present in trace amounts, but not as a dominant component. Therefore, the best choice is hydrogen.
