Answer: (A)

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, which are tightly packed together at the center of the atom.
3. Recognize that the cloud surrounding the nucleus is where electrons are found; these particles move around the nucleus in regions called orbitals.
4. Note that alpha particles are not subatomic particles within an atom but are actually helium nuclei emitted during radioactive decay.
5. Conclude that the subatomic particles found in the cloud surrounding the nucleus are electrons.
