Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
In $F e S_{2}$ , the oxidation number of iron is $+ 2$ .
For neutral molecules, the sum of the oxidation numbers is zero.
Thus, the sum of the oxidation numbers of $2$ sulphur atoms will be $- 2$ . The oxidation number of each S is $- 1$ in $(S - S)^{2 -}$ ion.
