As carbon content increases, which properties also increase?

Explanation:
Increasing carbon content in steel raises strength and hardness. This happens because more carbon forms harder microstructures and carbide phases that impede dislocation movement, making the metal firmer and stronger. In contrast, higher carbon generally reduces toughness and ductility, and it can also make machining harder and can slightly diminish corrosion resistance. Since the property pair that truly increases with more carbon is strength and hardness, that combination best fits the question.
