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.
A. A was `C_(6)H_(5)I`
B. A was `C_(6)H_(5)CH_(2)I`
C. B was `C_(6)H_(5)CH_(2)I`
D. Additions was unnecessary
