Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Sodium and magnesium have a higher affinity towards oxygen than that of carbon because these are highly reactive metals. Hence, carbon can not reduce the oxides of $N a$ or $M g$ .
$N a$ or $M g$ are more reactive as compared to carbon.
