33.
option 3 is correct answer
explanation
there is four type of functional groups
carboxylic aicd is stronger acid then phenol
phenols are stronger acid than alcohol
aromatic ring is nuetral
in case of carboxylic acid after loosing the proton the resultant anion can stabilized by both the oxygens of the carboxylic acid
in case of phenol after loosing th eproton the resulatent anion can stabilize by only carbon atoms
so which is less is less acidic than carboxylic acid
if alcohol looses proton the resultant anion cant delocalize so which is even less acidic than above two
as told you benzene is completely nuetra so no more acidic hydrogen
