Butanal contains which functional group?

Butanal is an aldehyde, so its defining feature is the aldehyde functional group, a carbonyl carbon double-bonded to oxygen and bonded to a hydrogen at the end of the chain (the -CHO group). This means the molecule contains a carbonyl group (C=O) as its key functional feature. The other choices would require different groups not present here: a carboxyl group would be -COOH, a hydroxyl group would be -OH, and an amine group would be -NH2. The terminal carbonyl in butanal is what sets it apart as an aldehyde, and that carbonyl is the presence referred to in the correct option.
