A colourless aqueous solution contains nitrates of two metals, X and Y. When it was added to an aqueous solution of NaClNaClNaCl, a white precipitate was formed. This precipitate was found to be partly soluble in hot water to give a residue P and a solution Q. The residue P was soluble in aqueous NH3NH_3NH3​ and also in excess sodium thiosulphate. The hot solution Q gave a yellow precipitate with KIKIKI. The metals X and Y, respectively, are
  1. A
    Ag and Pb
  2. B
    Ag and Cd
  3. C
    Cd and Pb
  4. D
    Cd and Zn
