Any soluble lead(II) salt.........

Explanation:

So $solution A$ $"solution A"$ is the obvious choice.

And we could write the reaction as....................:

$P b {(N O_{3})}_{2} (a q) + H_{2} S O_{4} (a q) \to P b S O_{4} (s) ⏐ ↓ + 2 H N O_{3} (a q)$ $Pb(NO_3)_2(aq) + H_2SO_4(aq) rarr PbSO_4(s)darr+ 2HNO_3(aq)$

This is a very poor multiple choice question (most multiple choice questions are!), because I am willing to bet that sulfuric acid added to lead carbonate would decompose the carbonate, bring the salt briefly up into solution, and then the insoluble lead sulfate would precipitate:

$P b C O_{3} (s) + H_{2} S O_{4} (a q) \to P b S O_{4} (s) ⏐ ↓ + C O_{2} (g) ↑ ⏐ + H_{2} O (l)$ $PbCO_3(s) + H_2SO_4(aq) rarr PbSO_4(s)darr+CO_2(g)uarr +H_2O(l)$

The oxide is possibly too insoluble. I might do this reaction tomorrow to see if I am right.
