The product $(B)$ will be:

The product $(A)$ is

Phenol on reaction with aqueous solution of bromine gives

What will be the product of the reaction with $HBr$?

Given below are two statements:
Statement $I$: Phenol on treatment with $CHCl_3 / aq. KOH$ under refluxing condition,followed by acidification produces $p$-hydroxybenzaldehyde as the major product and $o$-hydroxybenzaldehyde as the minor product.
Statement $II$: The mixture of $p$-hydroxybenzaldehyde and $o$-hydroxybenzaldehyde can be easily separated through steam distillation.
In the light of the above statements,choose the correct answer from the options given below:

Consider the following reactions:
$C_6H_5N_2Cl$ $\xrightarrow{H_2O, 283 \ K} X$ $\xrightarrow{Conc. \ HNO_3} Y$
$X \xrightarrow{Br_2/H_2O} Z$
$Y$ and $Z$ respectively are:
