Explanation:

A hydrogen bond is an attractive force between a hydrogen atom (covalently bonded to an electronegative atom like O, N, F) and an electronegative atom of another molecule. Option B matches this definition. A is about water molecule formation (covalent bonds), C is incorrect (H atoms don't bond this way), D is nonsense.

B) When a positive hydrogen atom bonds with a negative atom of another molecule.
