Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
$M n O_{4}^{-}$ oxidizes both $F e^{2 +}$ as well as $C_{2} O_{4}^{2}$ .
The reactions are given below:
$2 M n O_{4}^{-} + 5 H_{2} C_{2} O_{4} \to 2 M n^{2 +} + 10 C O_{2} + 8 H_{2} O$
$M n O_{4}^{-} + 5 F e^{2 +} + 8 H^{+} \to 5 F e^{3 +} + M n^{2 +} + 4 H_{2} O$
Thus, $5$ mol of $F e C_{2} O_{4}$ is oxidized by $3$ mol of $M n O_{4}^{-}$ in acidic medium.
So, $1$ mol of $F e C_{2} O_{4}$ is oxidized by $0.6$ mol of $M n O_{4}^{-}$ in acidic medium.
Thus, both assertion and reason are correct and reason is the correct explanation for assertion.
