In a neutral atom, the number of electrons is equal to the number of protons. This is because the positive charge of the protons in the nucleus is exactly balanced by the negative charge of the electrons orbiting around the nucleus. The number of neutrons can vary within an atom, but it does not affect the overall charge of the atom, which is neutral. Therefore, choices B, C, D, and E are all incorrect.
