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].

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 the energy of hydrogen bond that is formed with HF, H2​O and NH3​
 
  HF 10kcal/mol 
 H2​O  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].
