Options

  1. Aa metal
  2. Ba semiconductor
  3. Can insulator
  4. DNone of the above

Correct answer

A. a metal

Step-by-step solution

In metal, either there is no energy gap between the condition band which is partially filled with electrons and valence band or the condition band and valence band overlap each other.
