Which statement is 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.No
