Answer:
2). Increases
Explanation:
The hardness of the steel is directly associated with its tensile strength. The harder the steel is, the increased is its tensile strength would be. As the content of carbon in steel rises and thus, the steel is classified as per the amount of carbon in it like low carbon steel, high carbon steel, etc. Hence, the higher carbon content leads to an increase in the hardness of the steel and so in its ductile strength.
