The nucleus of a tritium atom, 3H, contains two neutrons and one proton.

Explanation:
- Tritium is a radioactive isotope of hydrogen. It has a mass number of 3 and an atomic number of 1, which means it has one proton in its nucleus.
- The mass number of an atom is the sum of its protons and neutrons. Therefore, the nucleus of tritium must contain two more particles to make up its mass number of 3.
- Since the charge of the nucleus is determined by the number of protons it contains, tritium's nucleus must have one proton.
- Therefore, the remaining two particles in tritium's nucleus must be neutrons, making the answer option D - two neutrons and one proton.
