Which of the following compounds will give a positive iodoform test?

The compound $A$ in the following reaction is:
$A$ $\xrightarrow[(ii) Conc. H_2SO_4 / \Delta]{(i) CH_3MgBr / H_2O} B$ $\xrightarrow[(ii) Zn / H_2O]{(i) O_3} C + D$
$D \xrightarrow[Ba(OH)_2, \Delta]{} CH_3-C(CH_3)=CH-CO-CH_3$

$Ph-CH_3$ $\xrightarrow{CrO_2Cl_2} (A)$ $\xrightarrow{conc. KOH} Ph-CH_2OH + (B)$
Product $(B)$ of the above reaction is:

Acetone is treated with excess of ethanol in the presence of hydrochloric acid. The product obtained is

$2,4-DNP$ test can be used to identify:

Match List-$I$ with List-$II$.

List-$I$ (Reactions)	List-$II$ (Reagents)
$(A)$ $CH_3(CH_2)_5COOC_2H_5 \rightarrow CH_3(CH_2)_5CHO$	$(I)$ $CH_3MgBr, H_2O$
$(B)$ $C_6H_5COC_6H_5 \rightarrow C_6H_5CH_2C_6H_5$	$(II)$ $Zn(Hg)$ and conc. $HCl$
$(C)$ $C_6H_5CHO \rightarrow C_6H_5CH(OH)CH_3$	$(III)$ $NaBH_4, H^+$
$(D)$ $CH_3COCH_2COOC_2H_5 \rightarrow CH_3CH(OH)CH_2COOC_2H_5$	$(IV)$ $DIBAL-H, H_2O$
