Which of the following statements is (or are) true?

I Hydrogen bonds occur between two hydrogen atoms.
II Hydrogen bonding occurs between a hydrogen atom and an oxygen atom within a molecule.
III Hydrogen bonding requires a molecule containing a large atom.
IV Hydrogen bonding must be overcome for water to boil.

A. IV only
B. II and IV only
C. I and III only
D. II and III only

I think that it is II and IV only. What do you think?
