The correct answer is A. Reduction.

Explanation:

The process of extracting a metal from its ore is called reduction. This is because the metal ion in the ore is reduced (it gains electrons) to form the neutral metal. The reducing agent is typically a form of carbon, such as coke (carbon made from coal), charcoal, or even carbon monoxide.

For example, in the extraction of iron from its ore (iron(III) oxide), the iron(III) oxide is reduced to iron by carbon monoxide:

Fe2O3 + 3CO → 2Fe + 3CO2

In this reaction, the iron(III) oxide (Fe2O3) is reduced to iron (Fe), and the carbon monoxide (CO) is oxidized to carbon dioxide (CO2).

However, for more reactive metals (like aluminium or sodium), electrolysis is used instead of reduction with carbon. This is because these metals are so reactive that they cannot be reduced by carbon.
