**Question 3** **Predict the product of the following transformation.** The starting material is an aromatic ketone with additional phenyl and methyl groups. The transformation involves three steps: 1. Reagents: HS(CH2)3SH, p-TsOH (cat.), PhH, reflux 2. Reagents: t-BuCl, AlCl3 3. Reagents: RaNi, H2, EtOH The objective is to determine which compound (A, B, C, D, or E) is the final product of the reaction sequence. **Options:** - **A**: Contains a phenyl group attached to a tert-butyl group and a methyl group. - **B**: Similar to A but with a different aromatic substitution pattern. - **C**: Features a thioether linkage (S-S) and a tert-butyl group. - **D**: Contains a ketone functional group, a tert-butyl group, and a methyl group. - **E**: Similar to D but with a cycloalkyl group instead of a direct aromatic substitution. **Choices:** 1. A 2. B 3. C 4. D 5. E The student needs to choose the correct option that represents the final product after applying the given reagents on the starting compound.
