The solution contains four ions

Ca2+, Na+, OH−, and CO3^-2

so there are following four combinations are possible

NaOH : this is highly soluble in water so will not form precipitate

Ca(OH)2: this is highly soluble in water so will not form precipitate

Na2CO3: again soluble in water so will not form precipitate

CaCO3 : this is not soluble in water (it has low solubility product) so this will form precipitate most likely

The compounds that can be formed by using only the cations and anions found in the item above are as follows: (1) Ca3(CO2)2, Na3CO2, NaOH, Ca(OH)2

The last two in the given are in aqueous phase. We are then left with the first two choices. Ca3(CO2)2 is exhibits a phase that is in solid form.

Hence, the answer to the question is Ca3(CO2)2
