What is the important use of coke?

Correct option is D

The correct answer is (d) As a reducing agent in the extraction of metals.
· Coke is primarily used as a reducing agent in the extraction of metals, particularly in the blast furnace for the production of iron. Coke helps in reducing the metal oxides to the pure metal by providing carbon, which reacts with the oxygen in the metal oxide.
Information Booster:
· As a fuel for industrial boilers : While coke can be used as a fuel, its primary role is in metallurgy as a reducing agent.
· As an oxidizing agent : Coke is a reducing agent, not an oxidizing agent.
