Correct Answer - Option 2 : high degree of plasticity

Explanation:

Malleability

  • Malleability is the property by virtue of which a material may be hammered or rolled into thin sheets without rupture.
  • This property generally increases with the increase of temperature.
  • Malleability is the ability of a metal to exhibit large deformation or plastic response when being subjected to a compressive force.
  • Lead, soft steel, wrought iron, silver, copper and aluminum are some materials in order of diminishing malleability.
  • Graphite is soft (Van der Walls forces) between two sheets of carbon atoms. But It is not malleable like metal, because of lack of plastic deformation (no dislocation movement in its structure).
