Answer»

Correct option  (d) I- > I > l+

Explanation:

Anions are always larger as compared to the corresponding parent atom as the effective nuclear force of attraction decreases per electron, while on losing an electron (cation formation), size shrinks as effective nuclear charge increases per electron.
