Correct Answer - Option 3 : Iron
Concept:
Modulus of elasticity is also a measure of material's stiffness or resistance to elastic deformation. Elasticity is a property of an object or material indicating how it will restore it to its original shape after distortion.
Higher value of the Young modulus of metal indicated higher stiffness.
