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°C, while above 1350°C aluminium can reduce MgO. Reason R : The melting and boiling points of magnesium are lower than those of aluminium. In light of the above statements, choose most appropriate answer from the options given below :

1. Both A and R are correct, and R is correct explanation of A .
2. Both A and R are correct, but R is NOT the correct explanation of A .
3. A is correct R is not correct.
4. A is not correct, R is correct.

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