A
is not equal to the number of free electrons
B
is greater than the number of free electrons
C
is equal to the number of free electrons
D
is less than the number of free electrons
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
An intrinsic semiconductor, also called an undoped semiconductor, is a pure semiconductor. In intrinsic semiconductors the number of excited electrons and the number of holes are equal: n = p
