Question
The image presents a chemical reaction sequence depicting the transformation of an unknown starting material to a product labeled "P." The reaction sequence involves:

1. An initial reaction with HCl.
2. A reaction with tBuOK.
3. A process involving ozonolysis, represented as "1) O₃".
4. A reduction step with Me₂S, noted as "2) Me₂S".

The product "P" is a cyclohexane ring with a ketone group on the C2 position and an isopropyl group on the C6 position.

Below the reaction sequence, four potential starting materials, labeled (A) through (D), are shown as cyclohexene and cyclohexane derivatives:

- (A) Cyclohexene with a methyl ketone at the C2 position.
- (B) Cyclohexene with an isopropyl group at the C6 position.
- (C) Cyclohexane with a methyl group at the C6 position.
- (D) Cyclohexane with an isopropyl group at the C1 position.

The task is to identify which starting material would lead to the product "P" following the given sequence of reactions. 

The correct starting material is option (B), which is cyclohexene with an isopropyl group at the C6 position. The double bond allows for the reactions to proceed, ultimately leading to the formation of the ketone in product "P."
