Which of the following statements is correct:
Correct answer: C. Elasticity is that property of a body that allows it to retain its original shape and dimension after the stress is removed
- A. Elasticity is that property of body which enables body to regain its original dimension
- B. Elasticity is that property of a body that does not allow it to return to its original shape
- C. Elasticity is that property of a body that allows it to retain its original shape and dimension after the stress is removed
- D. Elasticity is that property of a body that obeys Hooke's law
Explanation
Elasticity is the ability of a deformed material body to return to its original shape and size when the forces causing the deformation are removed.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
