B Correct answer
Explanation

Correct answer. Polar molecular solids: In these solids, molecules of the substance are formed by polar covalent bonds which are held together by relatively stronger dipole-dipole interactions. On cooling and subjecting to high pressures the gases first liquefy and then solidify to yield polar molecular solids. Examples: Solid SO2, solid NH3 and solid HCl, Urea
