A Correct answer
Explanation

Steel is an alloy of iron and carbon, where carbon content typically ranges from 0.1% to 1.5%. This carbon content is crucial as it determines steel's hardness and strength - higher carbon makes steel harder but more brittle. Options B, C, and D suggest carbon percentages that are too high for standard steel; such compositions would result in cast iron (2-4% carbon) or unusable brittle material.
