The correct option is D $L i I$
Among the halides of $L i, L i I$ has highest covalent character.Among, the ions of halogen, iodide ion is largest in size and it has maximum polarisability. According to Fajan's rule, small cation, large anion and high charge value are favourable conditions for covalent character.
