As in case of alkali metals solubility increases down the group but decreases for alkaline earth metals.
Here the correct orders of solubility are
I. $C a C O_{3} > S r C O_{3} > B a C O_{3}$
II. $L i_{2} C O_{3} < N a_{2} C O_{3} < K_{2} C O_{3}$
III. $K_{2} C O_{3} < R b_{2} C O_{3} < C s_{2} C O_{3}$
