Strong acid will increase the solubility of any of the salts in which the anion is a base that reacts with the H^+. For example, CaSO4 will be increased with strong acid because the SO4^-2 reacts as follows:
SO4^-2 + H^+ ==> HSO4^-
and this is k2 for the reaction. k2 = 1.2E-2. It will NOT increase solubility of PbBr2 because Br^- + H^+ ==> HBr is a strong acid itself. As an added piece of information, and one which I'm relatively certain is not one of the answers, if the strong acid is HCl, the solubility of all of the salts you have identified above plus the AgCl and AuCl will increase because of the formation of complex ions if the HCl is concentrated HCl. AgCl2^-, AgCl3^-2 are two of the complexes with Ag ion. AuCl reacts in a similar fashion.
addition of a strong acid would increase the solubility of which of the following salts
AgCl
CaSO4
CdS
CaCO3
PbBr2
CaHPO4
Cd(OH)2
AuCl
