Option 3 : 3 only

Concept:

Maximum attainable surface hardness depends primarily on carbon content.
Maximum hardness and strength in small sections increases as carbon content increases, up to 0.7%.
Alloying elements primarily influence hardenability. They also influence other mechanical and fabrication properties including toughness and machinability.
