The carbon-12 (C-12) atom has six protons and six neutrons in its nucleus. In imprecise terms, one AMU is the average of the proton rest mass and the neutron rest mass. This is approximately 1.67377 x 10-27 kilogram (kg), or 1.67377 x 10-24 gram (g).

Explanation:

Carbon-12 Nucleus:
- The atomic mass unit (amu) is defined as one twelfth of the mass of an atom of carbon-12.
- The carbon-12 nucleus is used as the reference for atomic mass units, making it closest to one amu.

Oxygen-16 Nucleus:
- The oxygen-16 nucleus has a mass of approximately 16 amu, which is much larger than one amu.

6.022 x 10^23 Atoms of Hydrogen:
- Avogadro's number (6.022 x 10^23) represents the number of atoms or molecules in one mole of a substance, not the mass of one amu.

One Proton:
- The mass of one proton is approximately 1.0073 amu, which is close to one amu but not as exact as the carbon-12 nucleus.
Therefore, the mass of the carbon-12 nucleus is closest to one atomic mass unit (amu) and serves as the reference point for atomic mass units.
