(B) $4 LiNO_3 \xrightarrow{\Delta} 2 Li_2O + 4 NO_2 + O_2$ (anomalous behavior).$2 Ba(NO_3)_2 \xrightarrow{\Delta} 2 BaO + 4 NO_2 + O_2$.Thus,statement $(i)$ is correct.The solubility of alkaline earth metal sulphates decreases down the group due to a decrease in hydration enthalpy compared to the lattice enthalpy.Thus,$BaSO_4$ is less soluble in water than $CaSO_4$. Thus,statement $(ii)$ is correct.Alkaline earth metals dissolve in liquid ammonia to form a deep blue coloured solution.$M + (x + y) NH_3 \rightarrow [M(NH_3)_x]^{2+} + 2[e(NH_3)_y]^{-}$.Thus,statement $(iii)$ is incorrect.

Which of the following statement$(s)$ is/are correct?
$(i)$ $LiNO_3$ and $Ba(NO_3)_2$ both will give $NO_2$ on heating.
$(ii)$ $BaSO_4$ is less soluble in water than $CaSO_4$.
$(iii)$ Alkaline earth metals do not dissolve in liquid ammonia.
