Question

Which is an organic compound

carbon

protein

oxygen

water

Answer 1

Among the options listed, "protein" is an organic compound. Organic compounds are generally defined as compounds that contain carbon atoms in addition to hydrogen, and proteins are large molecules made up of long chains of amino acids, which contain carbon, hydrogen, oxygen, and nitrogen.

- Carbon is an element, not a compound.
- Oxygen is also an element.
- Water (H₂O) is a simple inorganic compound.

So, the correct answer is **protein**.
