Holes can exist in
Correct answer: D. All of the above
- A. Conductors
- B. Insulators
- C. Semiconductors
- D. All of the above
Explanation
Holes can exist in all types of materials: conductors, insulators, and semiconductors. In semiconductors, holes are essentially vacancies in the valence band that behave like positive charge carriers.

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.
