Hydrocarbons: JEE Main 2026 Chemistry question

"P" is a hydrocarbon of molecular formula:- $\mathrm{C_8H_{14}}$. On ozonolysis, "P" forms "Q". "Q" on treatment with alkali under reflux condition produces "R", which on treatment with $\mathrm{I_2/NaOH}$ gives a yellow precipitate. Acidification of the solution gives "S". The structure of "S" is given below:- [structure: cyclopentene ring with $\mathrm{-COOH}$ and $\mathrm{-CH_3}$ on the two double-bond carbons] The correct structure of "P" is
