Which of the following is an organic molecule? a. hydrogen gas b. glucose c. nitrous oxide d. water

Glucose is an organic molecule.

So the correct answer is B.

Hope this helps,

I don't know if I completely understand the question, but I believe the answer would be A. Hydrogen gas because the others are compounds that, although may form naturally, aren't pure to begin with. I'm sorry if I'm incorrect. I haven't heard this question worded this way.
