Explanation:

To determine which molecule in living things lacks carbon atoms, we analyze each option:

• Protein: Contains carbon (part of organic molecules with C, H, O, N, etc.).
• Carbohydrate: Contains carbon (composed of C, H, O).
• Fat: Contains carbon (lipids with C, H, O).
• Water: Chemical formula \(H_2O\), has hydrogen and oxygen, no carbon.

Answer:

The correct option is the one labeled "water" (the option with "water" as the text).
