Solution

The correct option is C Assertion is correct but Reason is incorrect
Alumina is converted into Al by reduction with carbon at high temperature.
Carbon has less affinity for oxygen than aluminum. Hence, it cannot remove oxygen from alumina.
Thus Assertion is correct but Reason is incorrect.
