Work Step by Step

We can rule out options a), b), and e) because they all start out with a metal, not a nonmetal. Calcium (Ca), potassium (K), and silver (Ag) are all metals. We can also rule out option d) because sulfur (S) is the last element in the series and should be a metalloid, but sulfur is a nonmetal. The only option left is c). We see that the first of the series is bromine (Br), a nonmetal. The second in the series is barium (Ba), a metal. The last in the series is germanium (Ge), a metalloid. This fulfills the requirements of the question.
