When aniline reacts with $NaNO_2$ and dil. $HCl$ at $0^{\circ} - 5^{\circ}C,$ the product formed is

$CH_3NO_2 \xrightarrow{Sn + HCl} CH_3X$,the '$X$' contains:

What is the product $(X)$ in the reaction $C_6H_5NH_2 + HCl + NaNO_2 \rightarrow (X)$?

In the reaction $C_6H_5CHO + C_6H_5NH_2 \to C_6H_5N=CHC_6H_5 + H_2O$,the compound $C_6H_5N=CHC_6H_5$ is known as

Given below are two statements:
Statement-$I$: In Hofmann degradation reaction,the migration of only an alkyl group takes place from carbonyl carbon of the amide to the nitrogen atom.
Statement-$II$: The group is migrated in Hofmann degradation reaction to an electron-deficient nitrogen atom.
In the light of the above statements,choose the most appropriate answer from the options given below:

The reaction of aniline with a mixture of concentrated $HNO_3$ and $H_2SO_4$ yields ......
