Given are two statements one is labelled as Assertion A and other is labelled as Reason R. Assertion A: Magnesium can reduce {\Al}_2 {\O}_3 at a temperature below 1350^{\circ} {\C}, while above 1350^{\circ} {\C}, while above 1350^{\circ} {\C} aluminium can reduce {\MgO}. Reason {\R} : The melting and boiling points of magnesium are lower than those of aluminium. n light of the above statements, choose most appropriate answer from the options given below: [28-Jun-2022-Shift-1]

Correct Answer is : Both A and R are correct, but R is NOT the correct explanation of A.

Both A and R are correct, and R is correct explanation of A.
