Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
If two half reaction with electrode potential $E_{1}^{o}$ and $E_{2}^{o}$ gives a third half reaction, then $E_{3}^{o} = E_{1}^{o} + E_{2}^{o}$ .
But $Δ G_{1}^{o} = - n F E_{1}^{o}$ and $Δ G_{1}^{o} = - n F E_{2}^{o}$ .
Hence, $Δ G_{3}^{o} = Δ G_{1}^{o} + Δ G_{2}^{o}$
Thus, Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
