Step-by-step explanation:

Ketone is R-CO-R' Which is D

A is R-CHO

B is R-COO-R'

C is R-COOH

Answer 2

Answer : The correct option is, (D)

Explanation :

A ketone is an organic compound which contain a functional group with (-CO) i.e R-CO-R'

R-CO-R' functional group consists of a carbonyl center that means a carbon which is double-bonded to the oxygen. The carbon of this carbonyl group bonded with a carbon chain, (R) to one end and a carbon chain, (R') to another end.

For example :
`H_3C-CO-CH_3`

In the given options we conclude that, option D is a ketone.

Hence, the correct option is, (D)
