Answer 4

When you look at all 4 of these elements on a periodic table, they all fall under the family name halogens. Halogens are highly reactive nonmetals and go through phase changes.

According to this description, it would be wise to say that the correct answer would be B.

I attached a picture of the periodic table for future references.
