$O$

Vedclass · Answer

(A) The correct answer is $A$. Electronegativity decreases down a group in the periodic table as the atomic size increases and the valence electrons are further from the nucleus. For Group $16$ elements,the electronegativity values are as follows:    Element Electronegativity   $O$ $3.5$   $S$ $2.5$   $Se$ $2.4$   $Te$ $2.1$   $Po$ $2.0$    Thus,$O$ (Oxygen) has the highest electronegativity.
