B Correct answer
Explanation

Steel production requires iron ore as the primary mineral, coal as both fuel and reducing agent, and manganese as a key alloying element that improves strength, hardness, and removes impurities like sulfur. While limestone is crucial in steelmaking as a flux to remove silica impurities, the question specifically asks for minerals used 'in' steel - meaning the final product composition, where manganese is an essential alloying mineral.
