Ortho-nitrophenol is steam volatile whereas para-nitrophenol is not. This is due to:

AIntramolecular hydrogen bonding present in ortho-nitrophenol
Correct Answer
BIntermolecular hydrogen bonding
CIntramolecular hydrogen bonding present in para-nitrophenol
DNone of these

Solution

The ortho and para isomers can be separated by steam distillation. o-nitrophenol is steam volatile due to intramolecular hydrogen bonding while p-nitrophenol is less volatile due to intermolecular hydrogen bonding which causes the association of molecules.
Intramolecular hydrogen bonding takes place in ortho-nitrophenol because of the $$NO_2$$ and $$OH$$ molecules close proximity to each other.

Hence, option $$A$$ is correct.
