Most organic molecules contain a combination of carbon, hydrogen, nitrogen, and/or oxygen. Ocasionally, the amino acids in the oragnic molecules will also have other elements in them.

So, if any of the answer choices you were given are not any of the elements I just listed, that is the answer to your question.
