The ratio of bulk strain to bulk stress is called
Correct answer: D. Compressibility
- A. Young's modulus
- B. Bulk modulus
- C. 3D
- D. Compressibility
Explanation
The correct answer is Compressibility. Compressibility is defined as the reciprocal of the bulk modulus, which means it is the ratio of bulk strain to bulk stress. In contrast, the bulk modulus is the ratio of bulk stress to bulk strain, and Young's modulus pertains to tensile stress and strain. '3D' is not applicable to this context.

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.
