Which of the following substances possesses the highest elasticity?
Correct answer: A. Rubber
- A. Rubber
- B. Steel
- C. Glass
- D. Copper
Explanation
Rubber possesses the highest elasticity among the given options. It can undergo significant deformation under stress and return to its original shape when the stress is removed. This property is due to the molecular structure of rubber, which allows its polymer chains to stretch and then recoil.

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.
