I had been asked this question by my college director while I was bunking the class.

My enquiry is from Fick’s Law, Carbon Steels in section Diffusion in Solids & Ferrous Materials of Engineering Material & Metallurgy

Answer 1

The correct option is (a) Iron and Carbon

Easy explanation: Steels are alloys having primary components as Iron and Carbon. They, however, contain elements such as silicon, manganese, phosphorous, and sulfur in varying quantities. These elements are added either intentionally, or retained during the refining process.
