The stress-strain curves are drawn for two different materials X and Y. It is observed that the ultimate strength point and the fracture point are close to each other for material X but are far apart for material Y. We can say that materials X and Y are likely to be (respectively),
A. Plastic and ductile
B. Ductile and brittle
C. Brittle and ductile
D. Brittle and plastic
