Final Answer :
D
Explanation :
The smallest unit of any element is an atom, which is the basic building block of matter. Molecules are made up of atoms, but atoms themselves cannot be broken down into smaller units. Compounds are made up of two or more elements chemically bonded together, while macromolecules are large, complex molecules made up of smaller units called monomers. Electrons are subatomic particles that are one component of atoms.
