Answer 1

The correct option is A (A) $\to$ (iv), (B) $\to$ (iii), (C) $\to$ (ii), (D) $\to$ (i).

A. For high electropositive metals, electrolysis method is used for refining.

B. Copper is self-reduced from ${Cu}_{2}S$ and ${Cu}_{2}O$.

C. Iron is purified from Carbon Monoxide reduction.

4. Zinc is purified by reacting Zinc ore with Carbon.
