The atomic number is equal to the number of protons
Answer is: C) N.
Nitrogen (N) has greatest electronegativity.
Electronegativity (χ) is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.
Atoms with higher electronegativity attracts more electrons towards it, electrons are closer to that atom.
Nitrogen has electronegativity χ = 3 and other elements have less.

Explanation:
Hello!
In this case, we can notice that among the given ions, Mg2+ and Cr4+ are cations and I- and O2- are anions, thus, for each resulting compound we switch the oxidation states as subscripts to get:
