Explanation:

• A molecule can be composed of many elements (e.g., a water molecule, $\ce{H2O}$, has hydrogen and oxygen from different elements).
• A molecule cannot be made of a single atom because a molecule is a group of two or more atoms bonded together (a single atom is just an atom, not a molecule).
• A molecule can be made of a single element (e.g., $\ce{O2}$ is a molecule made of the element oxygen, with two oxygen atoms bonded together).

Answer:

• many elements
• a single element
