From the following flowsheet for the extraction of pure metal, answer the given questions.

(v) Reduction of oxides to elements with carbon generally takes place at high temperature, hence `Al` is used in aluminothermite process. It is because :

A

`Al` is more electropositive than the other metals (to be formed by reduction).

B

`Al` has maximum affinity for oxygen.

C

Reduction is highly exothermic, and the heat liberated makes the process spontaneous.

D

Reduction is highly endothermic, and the heat absorbedmakes the process spontaneous.
