To determine which particle(s) are most likely present in the nucleus of the atom, let's analyze the given information about each particle's charge:

1. Particle A: has a positive charge.
2. Particle B: has no charge (neutral).
3. Particle C: has a negative charge.

In an atom, particles found in the nucleus are primarily protons and neutrons:
- Protons have a positive charge.
- Neutrons have no charge.

Electrons, which have a negative charge, are not found in the nucleus. Instead, they orbit around the nucleus.

Based on this information:
- Particle A, having a positive charge, corresponds to a proton.
- Particle B, having no charge, corresponds to a neutron.
- Particle C, having a negative charge, corresponds to an electron, which is not found in the nucleus.

From the options provided:
- "Only particle A": Correct, since protons (positively charged) are found in the nucleus.
- "Only particle C": Incorrect, as electrons (negatively charged) are not found in the nucleus.
- "Both particles A and B": Incorrect, since both protons and neutrons are found in the nucleus, but we are looking for "most likely" based on usual convention (protons being most illustrative).
- "Both particles B and C": Incorrect, as electrons (negatively charged) are not found in the nucleus.

Thus, the particle most likely present in the nucleus of the atom is "Only particle A."
