Correct option: A.
${C_2}{H_5}OH$

Hydrogen bonding is maximum in ethanol.

Hydrogen bonding is observed when $H$ atom is attached to more electronegative $N , F$ or $O$ atom.

Thus, hydrogen bonding is possible in ethanol and triethylamine.

In ethanol, $H$ is attached to a more electronegative oxygen than in triethylamine, in which $H$ is attached to a less electronegative nitrogen.

Moreover, in triethyl amine, the $+ I$ effect of three methyl groups decreases the extent of hydrogen bonding.
