alcohol.

ester.

amine.

carboxylic acid. <-- this was the answer.

Answer 1

yes. it is COOH. C=O is carbonyl and OH is hydroxyl

Answer 2

Answer: Option (d) is the correct answer.

Explanation:

A carbonyl group is a group that contains a carbon atom attached to an oxygen atom through a double bond, that is, C=O.

Whereas a hydroxyl group is a group that contains oxygen and hydrogen atom attached by a single bond, that is, O-H.

Therefore, when carbonyl and hydroxyl group combine together then it results in the formation of COOH group which is known as a carboxylic group.
