According to the solubility rules, AgCl is insoluble in solutions containing Cl- ions and slightly soluble in solutions containing NO3- ions. Therefore, the least soluble solution would be the one with an ion that does not form a soluble compound with Ag+ or Cl-. BaCl₂ is the only option that fits this criteria, as BaAgCl_{2 and BaCl2} are both insoluble.
