Answer:

Hydrogen bonding occurs where hydrogen is bound to a strongly electronegative element such as fluorine, or oxygen, or nitrogen. The hydrides of these elements (which we call what?) have elevated normal boiling points.

Explanation:

#B.# #"Hydrogen bonding"# is the dominant intermolecular force of attraction. #"Dipole-dipole bonding"# is secondary. #"Dispersion forces"#, possessed by all molecules is the least potent intermolecular force.
