Correct answer: A. CO
- A. CO
- B. C-COO-C
- C. HCOH
- D. HOH

A keto group contains a carbonyl group within the carbon chain and is represented as C=O, commonly shortened in such options to CO. The likely mistake is HCOH, which resembles part of an aldehyde or hydroxyl-containing structure but does not represent a ketone carbonyl group.
