Compound $D$ is

How many of the transformations given below would result in aromatic amines?

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

List-$I$ (Mixture of Compounds)	List-$II$ (Reagent used to distinguish)
$A$. Diethyl amine + Ethyl amine	$I$. Bromine water
$B$. Acetaldehyde + Acetone	$II$. $CHCl_3 + KOH, \Delta$
$C$. Ethanol + Phenol	$III$. Neutral $FeCl_3$
$D$. Benzoic acid + Cinnamic acid	$IV$. Ammonical silver nitrate

Consider the following reaction sequence:
$p$-Nitrotoluene $\xrightarrow{P} Q$ $\xrightarrow{R} S$ $\xrightarrow{H_2O} T$
$S \xrightarrow{U} \text{Benzoic acid}$
Identify the correct statements from the following:
$(A) P = H_2/Pd, \text{ethanol}; R = NaNO_2/HCl; U = 1. H_3PO_2, 2. KMnO_4-KOH, \text{heat}$
$(B) P = Sn/HCl; R = HNO_2; S = p-\text{toluenediazonium chloride}$
$(C) S = p-\text{toluenediazonium chloride}; T = p-\text{cresol}; U = 1. CH_3CH_2OH, 2. KMnO_4-KOH, \text{heat}$
$(D) Q = p-\text{nitrobenzoic acid}; R = H_2/Pd, \text{ethanol}; T = p-\text{cresol}$
Which of the following combinations is correct?

Given below are two statements:
Statement $I$: $o$-Phenylenediamine can be synthesized from $o$-xylene using simpler reagents in the order: $i)$ Acidic $KMnO_4$,$ii)$ Ammonia,$iii)$ Bromine and alkali.
Statement $II$: Aniline can be converted into benzene using reagents in the order: $(i)$ Bromine-$H_2O$,$(ii)$ $NaNO_2 / HCl$ $(0-5^{\circ} C)$,$(iii)$ aq. $H_3PO_2$.
In the light of the above statements,choose the correct answer from the options given below.
