Answer: (A)

Verified step by step guidance

1. Understand the definition of oxidation in chemistry: Oxidation is the process where an atom, ion, or molecule loses electrons.
2. Recall that electrons are negatively charged particles that can be transferred during chemical reactions, especially redox reactions.
3. Recognize that protons and neutrons are components of the nucleus and are not lost or gained during oxidation or reduction processes.
4. Identify that atoms themselves are not lost in oxidation; rather, it is the electrons that are lost from the atom or ion.
5. Conclude that oxidation specifically refers to the loss of electrons.
