Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
$Δ G = Δ H - T Δ S$

For non-spontaneous reaction $Δ G > 0$ and for spontaneous reaction $Δ G < 0$ .

And if both $Δ H$ and $Δ T$ are positive for the reaction will be spontaneous only when $T Δ S$ exceeds $Δ H$ and it can happen at the higher temperature.
