(D) The iodoform test is given by compounds containing the $CH_3CO-$ group or the $CH_3CH(OH)-$ group.$(1)$ Ethyl methyl ketone $(CH_3COCH_2CH_3)$ contains the $CH_3CO-$ group, so it gives a positive test.$(2)$ Isopropyl alcohol $(CH_3CH(OH)CH_3)$ contains the $CH_3CH(OH)-$ group, so it gives a positive test.$(3)$ $3-	ext{Methyl} - 2 - 	ext{butanone}$ $(CH_3COCH(CH_3)_2)$ contains the $CH_3CO-$ group, so it gives a positive test.$(4)$ Isobutyl alcohol $((CH_3)_2CHCH_2OH)$ does not contain either the $CH_3CO-$ or the $CH_3CH(OH)-$ group. Therefore, it does not respond to the iodoform test.
