Answer By exposing materials to a hot flame (from a Bunsen
burner typically), the color of the flame can be used to identify
the material. Certain elements give off a characteristic color when
heated to high temperature. See the Related Links for "Wikipedia:
flame test" to the bottom for the answer.

(Explanation): remember that if an atom has less than 20 protons, the closer the number of neutrons and protons are, the more stable it is. Since 10 is closest to 12 out of these options, D is the correct answer.
