Answer: Option (d) is the correct answer.
Explanation:
A ketone is an organic functional group that contains a carbon and oxygen atom bonded together through a double bond, that is, C=O.
For example, acetone [tex]CH_{3}-CO-CH_{3}[/tex] is a ketone.
Whereas a hydrocodone is a drug which is used to relieve from moderate to sever pain.It is mostly combined with other drugs and resulting in a chemical formula [tex]C_{18}H_{21}NO_{3}.C_{4}H_{6}O_{6}[/tex].
A camphor is a volatile white color substance with chemical formula [tex]C_{10}H_{16}O[/tex]. It has aromatic smell and its taste is bitter.
A menthone is also an organic compound with chemical formula [tex]C_{10}H_{18}O[/tex].
Thus, we can conclude that out of the given options the simplest ketone used as an organic solvent is acetone.
