• A. Proton
• B. Neutron
• C. Electron cloud
• D. Nucleus

Answer: (D)

Verified step by step guidance

1. Recall the basic structure of an atom, which consists of a nucleus and an electron cloud surrounding it.
2. Understand that the nucleus contains protons and neutrons, while the electron cloud contains electrons.
3. Know the charges of each subatomic particle: protons carry a positive charge, neutrons are neutral (no charge), and electrons carry a negative charge.
4. Since protons are positively charged and are located in the nucleus, the positive charge of the atom is carried by the protons in the nucleus.
5. Therefore, the part of the atom that carries a positive charge is the nucleus, specifically due to the presence of protons.
