Could someone tell me why the answer to this problem is C?

Isn't Ag_2(SO_4) also insoluble? My professor didn't mention how to determine which compound is more/less soluble in water.

Calculate solubility from solubility product for Ag2SO4 and PbCl2

Answer C is wrong. Both compounds show the same type of solubility product hence without calculation you may decide - lower Kso = lower solubility.
