Solution

The correct option is B
Ph - COOH

No H-bonding in $C H_{3} - O - C H_{3}$
The more electronegative atom the H-atom is attached, stronger is the H-bond.
In case of $P h - O H$ or $C_{6} H_{5} - O H$ and in case of $C_{2} H_{5} O H$ , one hydrogen atom is attached to one oxygen atom.
The possible places of H-bonding are

In case of $C_{6} H_{5} - C O O H$ , the possible places of H-bonding are

Thus, H-bonding is maximum in Ph - COOH
