Explanation:
In India, the steel production industry requires the import of coking coal. Coking coal is a type of coal that is used in the process of manufacturing steel. It is used as a fuel and a reducing agent in the production of iron and steel. Since India does not have abundant reserves of high-quality coking coal, it needs to import it to meet the requirements of its steel industry.
Saltpetre (a type of potassium nitrate) and rock phosphate are not directly related to the steel production industry. Saltpetre is primarily used in the production of fertilizers and explosives, while rock phosphate is a key ingredient in the production of phosphate-based fertilizers.
