A compound \(A\) with molecular formula \(C_{10}H_{13}Cl\) gives a white precipitate on adding silver nitrate solution.  \(A\) on reacting with alcoholic \(KOH\) gives compound \(B\) as the main product. \(B\) on ozonolysis gives \(C\) and \(D.\) \(C\) gives Cannizaro reaction but not aldol condensation. \(D\) gives aldol condensation but not Cannizaro reaction. \(A\) is

1. A \(C_6H_5 - CH_2 - CH_2 - CH_2 - CH_2 - Cl\)
2. B \(\begin{array}{*{20}{c}}
