What is the product formed when phenol is treated with excess bromine water?

The major product of the following reaction is:

The major product in Reimer-Tiemann reaction is $X$. The reactants are $Y$ and $Z$. $X$,$Y$ and $Z$ are respectively.

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:

In the following reaction,the main product will be:

Reaction of phenol with dil. $HNO_3$ gives
