• D. Electron

Answer: (A)

Verified step by step guidance

1. Recall that an atom is composed of three main subatomic particles: protons, neutrons, and electrons.
2. Understand the charge of each particle: protons carry a positive charge, neutrons have no charge (neutral), and electrons carry a negative charge.
3. Identify that the question asks for the positively charged particle, so focus on the particle with a positive charge.
4. Recognize that the proton is the subatomic particle with a positive charge located in the nucleus of the atom.
5. Confirm that the correct answer is 'Proton' because it is the positively charged part of an atom.
