Stars in the halo are old, red, and dim, with fewer heavy elements. This is because they formed early in the universe's history when there were fewer heavy elements available. Our Sun, on the other hand, formed later in the Milky Way's history and has more heavy element material. Option A and B are incorrect as they both suggest young stars, which is not the case for halo stars. Option D is incorrect as it suggests halo stars have more heavy element material, which isn't the case either. Option E is incorrect as it suggests old, red, and bright stars, which is not what we observe in the halo.
