Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The oxidation curve which is lower in Ellingham diagram, is a better reducing agent.
So, reduction of ZnO with carbon is done at $1100^{\circ} C$ as it can be seen that the C-oxidation curve is lower at $1100^{o} C$ than that of Zn.
