Correct option is C
Steel containing less than 0.15% carbon content is known as dead mild steel. It is a very low-carbon steel, typically used where good formability, ductility, and weldability are required. This type of steel is known for its softness and is commonly used in the manufacturing of parts that do not require high strength but need to be easily shaped or welded.
It has low strength and is not suitable for high-stress applications.
