Answer: (B)

Verified step by step guidance

1. Recall the basic structure of an atom, which consists of a nucleus and electrons orbiting around it.
2. Understand that the nucleus contains subatomic particles responsible for most of the atom's mass.
3. Identify the subatomic particles: protons, neutrons, and electrons, and know their locations within the atom.
4. Recognize that protons and neutrons are located inside the nucleus, while electrons orbit outside the nucleus.
5. Conclude that the two subatomic particles found in the nucleus are protons and neutrons.
