A material that undergoes a large plastic deformation between its elastic limit and its fracture point is called
Answer: (A) ductile
Concept. The gap between the elastic limit and the fracture point on a stress–strain curve measures how much permanent (plastic) deformation a material can take.
Step 1. Classify. A large plastic region means the material can be drawn into wires or beaten into sheets: it is ductile (copper, aluminium). Brittle materials break soon after the elastic limit.
Answer. Ductile (Option A).
