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.
