The order of size of cation is, Na^2+>Zn^2+>Cu^2+.Therefore, the order of ionic character and hence, of solubility in water is as Na2s>ZnS>CuS.

Correct order of solubility in aqueous medium:
Explanation:
1. Na2S
- Na2S is highly soluble in water due to the presence of ionic bonds between sodium and sulfide ions.
- Upon dissolution in water, Na2S dissociates completely into Na+ and S2- ions, resulting in a high solubility.
2. ZnS
- ZnS is sparingly soluble in water as it forms a covalent bond between zinc and sulfide ions.
- The covalent nature of the bond in ZnS limits its solubility in water compared to ionic compounds like Na2S.
3. CuS
- CuS is the least soluble among the three compounds in water.
- It forms a predominantly covalent bond between copper and sulfide ions, leading to very low solubility in aqueous medium.
Therefore, the correct order of solubility in aqueous medium is:
Na2S > ZnS > CuS
