The correct statement is:

**A. A molecule can be composed of two or more atoms of the same element, like O2, or atoms of more than one element, like all compounds.**

This statement accurately describes that molecules can consist of either the same type of atoms (like O2) or different types of atoms (like water, H2O, which is a compound).
