Which molecule is classified as organic? a) water b) oxygen c) protein d) sodium chloride

The right answer to this question is option C. Protein

Explanation:

       First, what is an organic molecule? It's a molecule that contains Carbon in its composition, and by that, we'll jump into the options on the question. The first one is water, but as you can remember, there's no carbon in water's composition, only oxygen and hydrogen, so this is not a good option. The next one is oxygen, there's no carbon here too, so this is not good either. The last one it sodium chloride, and this one has no carbon either, only sodium and chlorine.

the correct answer is phenotype
