(C) The correct answer is $C$ (Oxygen). Electronegativity increases across a period from left to right and decreases down a group. Among the given elements ($C$,$Mg$,$O$,$S$),$O$ (Oxygen) is located in the second period and group $16$,making it the most electronegative due to its small atomic size and high effective nuclear charge.
