Correct Answer - A
Assertion:
`overset(+8)XeO_(6)^(4-)+overset(-1)(2F^(ө))+6H^(o+)rarroverset(+6)(Xe)O_(3)+overset(0)F_(2)+3H_(2)O`
Reason: The oxidation number of `Xe` decreases from `+8 "to" +6` in `XeO_(3)` while that of `F` increase from `-1` to zero. Therefore, `XeO_(6)^(4-)` is a stronger oxidant than `F_(2)`.
