Sulfur has six valence electrons, so it needs two more to complete its octet. It can achieve this by forming two covalent bonds with other atoms. Chlorine, on the other hand, has seven valence electrons and needs one more to complete its octet. It can achieve this by forming one covalent bond with another atom. Therefore, sulfur usually forms two covalent bonds (D) and chlorine usually forms one covalent bond (D).
