The correct answer is: Hydrogen bonding
Key Idea When $\mathrm{H}$ atom is directly linked with $\mathrm{N}$ or $\mathrm{O}$, or $\mathrm{F}$, inter or interamolecular $\mathrm{H}$-bonding is formed.
In between $\mathrm{CH}_3 \mathrm{OH}$ molecules intermolecular H-bonding exist.


Hence, it is the intermolecular H-bonding that must be overcome in converting liquid $\mathrm{CH}_3 \mathrm{OH}$ to gas.
