Answer:
c) Elastic Modulus
Step-by-step explanation
As we know that when deformation is under elastic limit then stress applied to the given material is proportional to the strain developed in it
So here we can say that since they both are directly proportional to each other so the proportionality constant here is known as Modulus of elasticity.
So we can say it is given as
so now if we draw a graph between between stress and strain then it must be a straight line and the the slope of this straight line is given as
So here correct answer will be
c) Elastic Modulus
