							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, H 2​	 O and NH 3​	   HF	10kcal/mol  H 2​	 O	 7Kcal/mol NH 3​	 	 2Kcal/molmeans to break the hydrogen of one mole HF molecules, 10Kcal energy is required.So the correct option is [A].
