Solution
The correct options are
A material A has a higher Young's modulus
D material A can withstand a greater stress
Young's modulus is represented by the slope of linear portion of stress-strain graph. Since slope of A is more, thus it has greater Young's modulus.
Ductility is how much a material can stretch without breaking after the elastic limit, i.e. the length of graph after elastic limit, which is clearly more for A.
The ultimate stress is given by the maximum stress on y-axis, which is larger for A (point Q) than B (point S).
