With excess bromine,phenol reacts to form:

Which of the following compounds is least likely to give effervescence of $CO_2$ in the presence of aqueous $NaHCO_3$?

In the given reaction,the compound $C$ is:
$C_6H_5OH$ $\xrightarrow{NaOH} (A)$ $\xrightarrow{CO_2, 140 \ ^oC, (4-7 \ atm)} (B)$ $\xrightarrow{HCl} (C)$

Given below are two statements:
Statement $I$: The acidic strength of monosubstituted nitrophenol is higher than phenol because of the electron-withdrawing nitro group.
Statement $II$: $o$-nitrophenol,$m$-nitrophenol,and $p$-nitrophenol will have the same acidic strength as they have one nitro group attached to the phenolic ring.
In the light of the above statements,choose the most appropriate answer from the options given below:

The major product of the following reaction sequence is:
$C_6H_5OH \xrightarrow[(ii) NaOH, (iii) H^+]{(i) CHCl_3, NaOH(aq)} ?$

Amongst the following,the total number of compounds soluble in aqueous $NaOH$ is:
