Answer:

Option B (S ^-2) is the correct answer

Explanation:

Sulfur or sulfur is a chemical element with symbol S and atomic number 16. It means that it has 16 protons and 16 electrons. But when an atom of Sulfur gains two electrons, a minus 2 charge comes over it. Therefore it becomes an ion. So if it gained two electrons its electrons become 18 that is why S-2 is the correct answer.
