Reference Answer
### (a) Ductility
**Definition:**
Ductility is the property of a material that enables it to be drawn out or elongated to an appreciable extent before rupture occurs. It is a measure of a material's ability to undergo significant plastic deformation under tensile stress without fracturing. This property is quantified in a tensile test by measuring the percentage elongation and the percentage reduction in cross-sectional area of the test piece at the point of fracture.
