Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Aluminium is extracted from bauxite by the electrolysis of molten mixture of Al 2 O 3 with cryolite. Reason (R): The oxidation state of Al in cryolite is +3. In the light of the above statements, choose the most appropriate answer from the options given below :

Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Aluminium is extracted from bauxite by the electrolysis of molten mixture of Al 2 O 3 with cryolite. Reason (R): The oxidation state of Al in cryolite is +3. In the light of the above statements, choose the most appropriate answer from the options given below : (A) (A) is true but (R) is false (B) (A) is false but (R) is true. (C) Both (A) and (R) are correct and (R) is the correct explanation of (A) (D) Both (A) and (R) are correct but (R) is not the correct explanation of (A)

(A) Aluminium is reactive metal so Aluminium is extracted by electrolysis of Alumina with molten mixture of Cryolite (B) Cryolite, Na 3 AlF 6 Here Al is in +3 O.S.

(A) is true but (R) is false

(A) is false but (R) is true.

Both (A) and (R) are correct and (R) is the correct explanation of (A)

Both (A) and (R) are correct but (R) is not the correct explanation of (A)

(A) Aluminium is reactive metal so Aluminium is extracted by electrolysis of Alumina with molten mixture of Cryolite (B) Cryolite, Na3​AlF6​ Here Al is in +3O.S.

(A) Aluminium is reactive metal so Aluminium is extracted by electrolysis of Alumina with molten mixture of Cryolite
(B) Cryolite, $N a_{3} A l F_{6}$
Here $A l$ is in $+ 3 O . S .$
