C Correct answer
Explanation

Atoms are the smallest units of elements that retain the element's chemical properties and do not undergo division by chemical means. Protons and neutrons are subatomic particles within the atom's nucleus, while molecules are formed when atoms chemically bond together. While atoms can undergo nuclear fission (splitting of the nucleus), this is a nuclear process, not chemical division. The atom as a complete unit cannot be divided through ordinary chemical processes.
