They both have 35 protons. They both have 35 electrons if they are electrically neutral

Molecular weights are the AVERAGES of abundance of all the isotopes possible, so since the molecular weight of bromine is almost exactly in between the masses of the two most abundance isotopes, they must exist in a nearly 50:50 ratio. I'd go with answer (D).
