Answer

$LiCl$ has a high melting point.

Work Step by Step

Ionic solids: Solids having formula units as composite units. Atomic solids: These solids have atoms as composite units. Molecular solids: These solids have molecules as composite units. Ionic solids have high melting points when compared to atomic and molecular solids. Because in ionic solids, intermolecular forces are stronger. In the given compounds: $Ar$ is an atomic solid. $CCl_{4}$ is a molecular solid. $CH_{3}OH$ is also a molecular solid. And $LiCl$ is an ionic solid. Hence $LiCl$ has a high melting point.
