The heavier members of 13 and 14 groups ...

The heavier members of `13` and `14` groups besides the group oxidation state also show another oxidation state. Down the group `(darr)`, the stability of higher oxidation state increases. This concept which is commonly called inert pair effect has been used to explain many physical and chemical properties of the element of these groups.
Which among the following is the strongest oxidising agent ?

A

`SnO_(2)`

B

`SiO_(2)`

C

`GeO_(2)`

D

`PbO_(2)`
