Answer is (C), NH3.
Ag+ in AgCl will react with NH3 to form a soluble complex, [Ag(NH3)2}+, but Pb2+ will not form the complex.
The other reactions all give a precipitate with similar visual properties for Ag+ and Pb2+, e.g. yellow precipitate with chromate (VI) ions as in answer (A).

Use ammonia as ammonium hydroxide. It will form a complex ion with the silver chloride and dissolve it.
It is in the books. That is how I learned it, forty years ago.
