From what are all matter composed?

Molecules
Cells
Atoms
Elements

The correct answer is: Atoms

Atoms are the fundamental units of all matter. Molecules are composed of multiple atoms bonded together, but cannot be considered the building blocks of matter as not all matter is composed of molecules. Cells are the basic units of life and are not responsible for the composition of inanimate matter. Elements are pure substances made up of only one type of atom, but matter is composed of a combination of elements. Therefore, atoms are the correct answer for what all matter is composed of.
