Options

  1. Aan insulator
  2. Ba metal
  3. Can intrinsic semiconductor
  4. Da superconductor

Correct answer

A. an insulator

Step-by-step solution

Insulators have large energy gap between valence and conduction band (about 6 eV ), while semiconductors have a smaller one and conductors, the smallest energy gap.
