In a conductor, there are many free electrons that can move around and conduct electricity. However, there are also many holes that can also conduct electricity. The number of holes is less than the number of free electrons, but they still play an important role in conduction.<\/p>\n<p>Option A is incorrect because there are not the same number of holes as free electrons.
