Bottles containing `C_(6)H_(5)I` and `C_(6)H_(5)-CH_(2)I` lost their original lables. They were labelled A and B for festing. A and B were separately taken in a test tube and boiled with `NaOH` solution. The end solution in each tube was made acidic with dilute `HNO_(3)` and then some `AgNO_(3)` solution was added. Substance B gave a yellow precipitate. Which one of the following statements is true for this experiment.

Two bottles containing C_6 H_5 I and C_6 H_5 CH_2 I lost their original labels.They were labelled as A and B for testing A and B were separately taken in test tubes and boiled with Na OH solution. The solution in each tube was made acidic with dilute HNO_3 and some AgNO_3 solution was added .Substance B gave a yellow precipitate. Which of the following statements is true for this experiment : Addition of HNO_3 was unnecessary, A was C_6 H_5 I , A was C_6 H_5 CH_2 I , B was C_6 H_5 I
