What is formed when benzylamine reacts with nitrous acid?

Aniline is purified by which of the following methods?

Which is the major product of the following reaction?

Tertiary amines have the lowest boiling points among isomeric amines because,

Given below are two statements :
Statement $I$: Aniline reacts with conc. $H_2SO_4$ followed by heating at $453-473 \ K$ to give $p$-aminobenzene sulphonic acid (sulphanilic acid). This compound contains both nitrogen and sulphur,and thus it gives a blood red colour in the 'Lassaigne's test' due to the formation of ferric thiocyanate,$[Fe(SCN)]^{2+}$.
Statement $II$: In Friedel-Craft's alkylation and acylation reactions,aniline forms a salt with the $AlCl_3$ catalyst. Due to this,the nitrogen atom of aniline acquires a positive charge and acts as a deactivating group,preventing further reaction.
In the light of the above statements,choose the correct answer from the options given below :

For the transformation shown below,the reagent used is:
$3-bromobenzenediazonium \ chloride \rightarrow \text{bromobenzene}$
