Which of the following has the highest $pK_{a}$ value?

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:

Write the Friedel-Crafts reaction of anisole.

The major product of the following reaction is:

$A$ solution of phenol in chloroform when treated with aqueous $NaOH$ gives compound $P$ as a major product. The mass percentage of carbon in $P$ is $..............$ (to the nearest integer)
(Atomic mass : $C = 12$; $H = 1$; $O = 16$)

Phenol does not react with which of the following?
