Answer:
A, F, H
Explanation:
Hydrogen bonding occurs between compounds that make N-H, O-H, and F-H bonds. Just because a compound has a N, O, and F atom in the molecule doesn't mean that the compound will exhibit hydrogen bonding. The N, O, or F must be bonded to a hydrogen. Carbon-hydrogen bonds do not cause hydrogen bonding.
This means that A, F, and H will have hydrogen bonding.
