CAIE A-Level Physics AS 6.1.5 The Terms Stress Strain and the Young Modulus Questions question 1

[Maximum number: 1]

Two wires, one made of brass and the other of steel, are stretched in an experiment. Both wires obey Hooke's law during this experiment.

The Young modulus for brass is less than the Young modulus for steel.
Which graph shows how the stress varies with strain for both wires in this experiment?
