Detailed Solution

Because oxides are converted to metals by carbon or oxygen in the smelting process, roasted or cachinnated ore is often burned with powdered coke in the presence of a flux. Slag is used to eliminate impurities.

Heat and a chemical reduction agent are used in smelting to break down the ore, removing other components as gases or slag and leaving just the metal left. The reducing agent is frequently a carbon source, such as coke.

Hence the correct option is A
