The correct answer is:
A positively charged nucleus is surrounded by one or more negatively charged electrons
The explanation:
when:
proton is a positively charged elementary particle that is a fundamental constituent of all atomic nuclei.
neutron is a subatomic particle found in the nucleus of every atom except that of simple hydrogen. The particle derives its name from the fact that it has no electrical charge
electron is a negatively charged subatomic particle. It can be either free (not attached to any atom), or bound to the nucleus of an atom .
so, , there are positively charged protons and zero-charged neutrons in the nucleus of an atom. Therefore, the nucleus is positively charged, Surrounding the nucleus, the electrons have negative charge.
Thus, the correct answer is (3): A positively charged nucleus is surrounded by one or more negatively charged electrons is correct.

Further explanation:
The smallest particle that is the building block of matter is known as an atom. Most of the space in an atom is empty, and its mass is concentrated inside a small region called the nucleus.
Protons, electrons, and neutrons are the three subatomic particles that are present in the atom. The sum of protons and neutrons are called nucleons because these are located in the nucleus of the atom. Electrons revolve around the nucleus in definite orbits. The positively charged subatomic particle is called proton. Neutron is a subatomic particle that has no charge. Electron is the negatively charged subatomic particle. The number of electrons is equal to the number of protons in a neutral atom.
As we know, the nucleus consists of protons and neutrons. Protons are positively charged whereas neutrons are neutral and therefore the overall charge on the nucleus becomes positive. Electrons are negatively charged species. These revolve around the nucleus in circular orbits. So a positively charged nucleus is surrounded by one or more negatively charged electrons. Hence statement (3) is correct, and the statement (1), (2) and (4) are incorrect.
