When a metal rod M is dipped into an aqueous colourless concentrated solution of compound N, the solution turns light blue. Addition of aqueous `NaCI` to the blue solution gives a white precipitate O. Addition of aqueous `NH_(3)` dissolves O and gives an intense blue solution. The compound N is:A. `AgNO_(3)`B. `Zn(NO_(3))_(2)`C. `AI(NO_(3))_(3)`D. `Pb(NO_(3))_(2)`
