Solution

The correct option is D Both (A) and (R) are correct but (R) is NOT the correct explanation of (A)
Lithium has smallest size among the alkali metal. So charge to size ratio of lithium is very high. Due to this lithium salts are hydrated in nature. LiCl is deliquescent and crystallises as a hydrate, LiCl.2H2O whereas other alkai metal chlorides do not form hydrates. Polarising power is related to covlent character.
