(C) The iodoform test is given by compounds containing the $CH_3CO-$ group or the $CH_3CH(OH)-$ group. $Diethyl \ ketone$ $(CH_3CH_2-CO-CH_2CH_3)$ does not contain the $CH_3CO-$ group,therefore it does not form a yellow precipitate of iodoform $(CHI_3)$.    $CH_3COCH_3 \xrightarrow{NaOH/I_2} CHI_3$ $Yellow \ ppt$   $C_2H_5OH \xrightarrow{NaOH/I_2} CHI_3$   $CH_3-CH(OH)-CH_3 \xrightarrow{NaOH/I_2} CHI_3$
