You are correct! This compound (methanol) forms the strongest hydrogen bonds of the available choices since oxygen is more electronegative than nitrogen. Although fluorine is more electronegative than oxygen there are no HF bonds in answer (d). Methanol also has some of the strongest dipole-dipole interactions of the available compounds although hydrogen bonding is the principle intermolecular attraction when a compound has an electropositive hydrogen atom and available non-bonding electron pairs.
