The correct option is (c) A is true but R is false.
Explanation:
Solubility of AgCl (at 25oC) in H2O = 0.0020 g AgCl per litre of H2O
Solubility of AgCl in NH3 (at 25oC) = 14.00 g AgCl dissolved per kg of NH3
Solubility of AgCl is more in NH3 due to formation of soluble stable complex [Ag(NH3)2]+.
Ammonia is less polar than water, as oxygen is more electronegative than nitrogen.
