A Correct answer
Explanation

The -CO- group (carbonyl group with carbon double-bonded to oxygen, flanked by two carbon atoms) is called a ketone. In organic chemistry, ketones are characterized by this R-CO-R' structure where carbon is bonded to two alkyl groups. Acids contain -COOH, esters have -COO-, and ethers have R-O-R structures, so the ketone identification is correct.
