Correct Answer - Option 1 : strength
Concept:
Toughness: The ability of the material to withstand stress (resist fracture due to high impact loads) without fracture is known as toughness. It is defined as the ability to absorb energy in the plastic state, so the toughness of the material represents its strength.
Malleability: It is the ability of a metal to exhibit large deformation or plastic response when being subjected to compressive force.
Elasticity: It is the property of a material to regain its original shape after deformation when the external forces are removed.
Plasticity: It is the property of a material that retains the deformation produced under load permanently. Thus, it is a property of a material that allows it to deform without fracture.
Ductility: The property of the material that allows it to be drawn into wires or elongated before failure is known as ductility.
Brittleness: The property of a material that produces fracture without any appreciable deformation is known as brittleness. It is the opposite of toughness.
