Dear student,

Among the F, O and N , Fluorine has the higher value of electronegativity, this is the reason that fluorine can form the strongest hydrogen bond with the H atom of another molecule.

Just take an idea from the value of energy of hydrogen bond that is formed with HF, H2O and NH3

HF	10kcal/mol
H2O	7Kcal/mol
NH3	2Kcal/mol

means to break the hydrogen of one mole HF molecules, 10Kcal energy is required.

So the correct option is [A].
