Carboxylic acid is more acidic than alcohol. Then phenol and ethanol is less acidic than chloroacetic and acetic acid. -I-effect increase the acidity. Therefore chloro acetic acid is more acidic than acetic acid. Phenol is more acidic than ethanol because phenonide ion show delocalization. Hence, the order of acidity isethanol $<$ phenol $<$ acetic acid $<$ chloroacetic acid

Electrophile that participates in nitration of benzene is
1 $\mathrm{NO}^{+}$
2 $\mathrm{NO}_{2}^{+}$
3 $\mathrm{NO}$
4 $\mathrm{NO}_{3}^{-}$
Explanation:
(B): In nitration of benzene, $\mathrm{NO}_{2}^{+}$is an electrophile.
