Assertion

In the species, $$S_{4}O_{6}^{2-}$$ each of the two extreme sulphurs exhibits oxidation state of $$+5$$ and the two middle sulphurs as zero.

Reason

The average of four oxidation numbers of sulphurs of the $$S_{4}O_{2-}^{6}$$ is $$2.5.$$.

A

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

B

Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
