Coke is obtained from the destructive distillation of coal.
Explanation:
Destructive distillation is the process of heating coal in the absence of air to obtain useful products such as coke, coal tar, and coal gas. In this process, coal is heated to a high temperature of about 1100°C in the absence of air. This causes the breakdown of complex organic compounds present in coal into simpler compounds. Coke is the solid residue left after the volatile components of coal are driven off during this process.
Coke is a hard, porous, and black substance that is used as a fuel and as a reducing agent in the production of iron and steel. It has a high carbon content and low impurities, which makes it a preferred fuel for industrial processes.
Therefore, the correct option is C - destructive distillation of coal.
