Bottles containing C6H5\mathrm{C}_6 \mathrm{H}_5C6​H5​ l and C6H5CH2I\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{I}C6​H5​CH2​I lost their original labels. They were labelled A\mathrm{A}A and B\mathrm{B}B for testing A\mathrm{A}A and B\mathrm{B}B were separately taken in test tubes and boiled with NaOH\mathrm{NaOH}NaOH solution. The end solution in each tube was made acidic with dilute HNO3\mathrm{HNO}_3HNO3​ and then some AgNO3\mathrm{AgNO}_3AgNO3​ solution was added. Substance B gave a yellow precipitate. Which one of the following statements is true for this experiment?
