In the following reaction,$C_6H_5CN$ $\xrightarrow[(ii) H_3O^+]{(i) SnCl_2/HCl} X$ $\xrightarrow{Dil. NaOH} Y$. Here,$X$ and $Y$ are:
- A$X = C_6H_5CH_2Cl, Y = \text{4-methylchalcone}$
- B$X = C_6H_5CH_2Cl, Y = \text{chalcone derivative}$
- C$X = C_6H_5CHO, Y = \text{4-methylchalcone}$
- D$X = C_6H_5CHO, Y = \text{4-methylchalcone}$ (with correct structure)
