Solution

The correct options are
A 2,4,6-Trimethyl phenol
B $C H_{3} O H$
D $H_{2} O$
In $2, 4, 6 - t r i m e t h y l p h e n o l$ and $C H_{3} O H$ methyl groups exhibit $+ I$ effect and decrease acidity. In $H_{2} O$ hydrogen bonding makes hydrogen less available and less acidic. But in $p - n i t r o p h e n o l$ the $- M$ effect of $N O_{2}$ group makes it more acidic than phenol.
