Bottles containing \[{{C}_{6}}{{H}_{5}}I\] and \[{{C}_{6}}{{H}_{5}}C{{H}_{2}}I\] lost their original labels. They were labelled X and Y for testing. X and Y were separately taken in a test tube and boiled with NaOH solution. The end solution in each test tube was made acidic with dilute \[HN{{O}_{3}}\] and then some \[AgN{{O}_{3}}\] solution was added. Substance Y gave a yellow precipitate. Which one of the following statements is true for this experiment?

A)  X was  \[{{C}_{6}}{{H}_{5}}I\]

B)  X was \[{{C}_{6}}{{H}_{5}}C{{H}_{2}}I\]

C)  Y was \[{{C}_{6}}{{H}_{5}}I\]

D)  Addition of His\[HN{{O}_{3}}\] was unnecessary.
