What might be true about the oldest stars in the Milky Way?

Question

Quizplus · Accepted Answer

The oldest stars in the Milky Way would have formed when there were few heavy elements, as there had not been enough time for earlier stars to create them through fusion and supernova explosions. Thus, the oldest stars would have few heavy elements.

Answer: D
 Since the oldest stars in the Milky Way formed early in the Universe's history, they would have formed from the earliest clouds of gas and dust, which were primarily composed of hydrogen and helium. These stars would have been massive, since they formed from such large, dense clouds.

Note: None of the other choices are accurate. Oldest stars are not expected to have lots of heavy elements (A), be supergiants (B), or be seen as pulsars (E).
