Identify the final product $D$ in the following reaction sequence: $CH_3CH_2Br$ $\xrightarrow[\Delta]{Aq. KOH} A$ $\xrightarrow[\Delta]{KMnO_4/H^+} B$ $\xrightarrow[\Delta]{NH_3} C$ $\xrightarrow[alkali]{Br_2} D$

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: Aniline on nitration yields ortho,meta and para nitro derivatives of aniline.
Reason $R$: Nitrating mixture is a strong acidic mixture.
In the light of the above statements,choose the correct answer from the options given below.

What is formed when benzoyl chloride reacts with aniline in the presence of sodium hydroxide?

Identify the product $A$ in the following reaction:
$[(CH_3CH_2CH_2)(CH_3CH_2)_3N]^+ OH^- \xrightarrow{\Delta, -H_2O} A + (CH_3CH_2CH_2)(CH_3CH_2)_2N$

Action of $HNO_2$ on $CH_3NH_2$ gives the following as the major product:
