detailed solution

Correct option is B

Hydrogen bond broadly classified as two types.

 Inter molecular hydrogen bonding    

Intra molecular hydrogen bonding

Inter molecular hydrogen bonding: This type of  hydrogen bond is formed Between two different molecules of same or different compounds.

Ex: HF, water and alcohol etc…

In water molecule, ${\mathrm{H}}_2\mathrm{O}$ ,  the hydrogen bond is formed between the highly E.N of oxygen of one molecule and hydrogen atom of other molecule.
