(D)The ion of Li and its compounds are more heavily hydrated than those of the rest of the group elements

Answer: (A)

Solution

Lithium's anomalous properties (arising from its very small size and high polarising power) include its comparatively high melting/boiling points (B), its unique ability to form a nitride directly with (C), and its unusually strong hydration of and its compounds (D) — all genuine
