Correct Option: A
The correct option is: is equal to the number of free electrons
In an intrinsic semiconductor, the number of holes is equal to the number of free electrons. In an intrinsic semiconductor, electrons can break covalent bonds and create holes. The number of holes is essentially equal to the number of free electrons, maintaining overall charge neutrality in the material.
