Solution

The correct option is A The stability of +2 oxidation state increases.
(B) The stability of +2 oxidation state increases.
Due to the increase in inert pair effect as we move down the group, s-orbital electrons stop participating in bonding in an atom which decreases the stability of +4 oxidation state and increases the stability of +2 oxidation state.
