C.
Work Step by Step
Hydrogens with partial positive charges on them (C.) can form hydrogen bonds, which are found in water but not limited to water, so B. is wrong. A. is incorrect since nonpolar bonds in things like hydrocarbons include hydrogen but cannot form hydrogen bonds due to the lack of a partial charge on hydrogen. D. only occurs in hydrogen gas, forming a nonpolar bond; thus, D. is wrong for the same reason as A.
