Correct Answer - Option 2 : Elasticity
Elasticity: The property by virtue of which a deformed body springs back to its original position after removing the external force is known as elasticity.
Plasticity: This is an ability of material to deform without any rupture by non returnable way. After removing the load there are staying permanent deformations.
Ductility is the ability of a material to withstand tensile force when it is applied upon it as it undergoes plastic deformation whereas Brittleness is the opposite of ductility as it refers to the ability of materials to break into pieces upon application of tensile force without any elongation or plastic deformation.
Tenacity is the property of metal to resist the fracture when under the action of tensile load. it refers to the ultimate tensile strength of the material, a metal having high tenacity means it has high tensile strength.
Melleability is that property by which a metal can be drawn into a thin sheet of negligible thickness.
