Which statements are correct?

A.The area under which the straight-line portion (elastic region) of the stress-strain curve is modulus of resilience.

B.Modulus resilience is a measure of the energy per unit volume that the material can absorb without plastic deformation.

C.Resilience tells you the capacity of a material to adsorb energy when it is deformed elastically and then, upon unloading, to have this energy recovered.

D.None of the above statement is correct.
