Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Consider the reaction, $2 S_{2} O_{3}^{2 -} + I_{2} \to S_{4} O_{6}^{2 -} + 2 I^{⊝}$ .
In this reaction, iodine is reduced as its oxidation number changes from 0 to -1.
S is oxidized as its oxidation number increases.
During oxidation, loss of electron takes place. During reduction, gain of electron takes place.
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
