Answer: Nickel(II)chloride

Explanation: As per solubility rules, except alkali metals and ammonium ion the carbonates, hydroxides and sulfides are mostly insoluble.

So, lead(II)carbonate, Iron(III)hydroxide and copper(II)sulfide are insoluble.

Chlorides are soluble. Hence, the only correct choice is nickel(II)chloride.

If we take a look at the solubility chart then it also makes this clear. Solubility chart could be found in the books and online also.
