Correct Answer: C) The ability of a material to be drawn into thin wires or stretched without breaking.
- Explanation: Ductility refers to a material’s ability to undergo significant plastic deformation before breaking, allowing it to be stretched into wires or other shapes. Ductile materials can be pulled into thin wires or elongated without breaking, which is a key characteristic of ductility.
Incorrect Options:
A) The ability of a material to absorb energy and deform without breaking.
- Explanation: This describes toughness rather than ductility. Toughness is the ability to absorb energy and deform plastically without fracturing, while ductility specifically refers to the material’s ability to undergo plastic deformation and be stretched into shapes.
B) The ability of a material to return to its original shape after being deformed.
- Explanation: This describes elasticity, not ductility. Elasticity is the property of a material to return to its original shape after deformation, whereas ductility is concerned with how much a material can deform plastically before breaking.
D) The tendency of a material to fracture or break with minimal plastic deformation.
- Explanation: This describes brittleness, not ductility. Brittle materials fracture with little plastic deformation, whereas ductile materials can undergo significant deformation before breaking.
