Explanation by: Shyam Dubey
Acetone (CH3-CO-CH3) contains a carbonyl group bonded to two carbon atoms — this is a ketone. An aldehyde has a carbonyl bonded to at least one hydrogen. Alcohols have an -OH group. Carboxylic acids have -COOH. Therefore ketone is correct and the other options are incorrect functional groups for acetone.
