Representative particles are smaller particles which represent larger particles.

Covalently molecules are made up of atoms and hence atoms are representatives. Examples are N2 , C60, H2

Cations and anions represent ionic compound like NaCl . Its representatives are Na+ cation  and Cl- anion

A representative particle is the type of particle that the substance is usually composed of. Representative particles are thus smallest units that have the same composition as the bulk material. One mole consists of Avogadro's number of representative particles of that material.

The representative particle of an element is an atom. The representative particle of a molecular compound is a molecule.

The representative particle of an ionic compound is its formula unit. One formula unit of an ionic compound is composed of a cation and an anion. Therefore, cations and anions are the representative particles of ionic compounds.

Thus, atoms, cations, anions - all are representative particles.

Answer to the given problem is option d) None of the above.
