Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. Assertion A: LiF is sparingly soluble in water. Reason R: The ionic radius of Li⁺ ion is smallest among its group members, hence has least hydration enthalpy. In the light of the above statements, choose the most appropriate answer from the options given below.

(A) Both A and R are true and R is the correct explanation of A.

(B) Both A and R are true but R is NOT the correct explanation of A.
