The correct option is phosphorus (P).
EXPLANATION: Chlorine, Cl is lies at the 3rd period of the periodic table. The other elements of 3rd period in the periodic table are Sodium (Na), Magnessium (Mg), Aluminum (Al), Silicon (Si), Phosphorous (P), Sulfur (S), and Argon (Ar). Of the given options, the only element belong to 3rd period is phosphorus (P)
