Which one of the following compounds shows the presence of intramolecular hydrogen bond?

Intramolecular Hydrogen bound
Hydrogen bond formed different parts of same molecule.
e.g., O- nitrophenol, O-hydroxybenzonic acid, O-hydroxy benzaldehyde, cellulose, cellulose is having hydrogen bonding and Van der waals forces.
Hydrogen bonds in cellulose
(1) Intra chain H-bonds between neighbouring monomers of a single cellulose polymers.
(2) Inter chain H-bond between adjacent chain.
Intermolecular H-bond
Formed between different molecules of same or different species.
e.g: HF, H₂O, NH₃, RCOOH
