Solution

The correct option is A $K F$
Among the given halides, the ionic character increases in the order: $K I < K B r < K C l < K F$

This can be figured out by using Fajan's rules. As the size of the anion increases, the covalent character increases. Since $K F$ is the most ionic among the given halides, it has the highest melting point.
