Hint: In ozone resonance takes place

A.
Hydrogen bonding is a special type of dipole-dipole attraction between molecules. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom.
Hence, HF show hydrogen bonding.

B.O₃ is known as ozone. In O₃ resonance takes place. The resonating structure of O₃ is as follows:

C. An ionic bond is formed by the complete transfer of some electrons from one atom to another.

Metal and non-metal combine and form ionic compound. In LiF, ionic bond is present.

D. Solid C is an example of covalent solid because atoms are connected with each other by covalent bonding.
