Statement I: `Pb^(4+)` compounds are stronger oxidizing agents than `Sn^(4+)` compounds.
Statement II:The higher oxidation states for the group 14 elements are more stable for the heavier members of the group due to ‘inert pair effect’.

A

If both (A) and (R) are correct and (R) is correct explanation of (A)

B

If both (A) and (R) are correct and (R) is not correct explanation of (A)

C
