An organic compound $X$ with molecular formula $C_{11}H_{14}$ gives an optically active compound on hydrogenation. Upon ozonolysis,$X$ produces a mixture of compounds $P$ and $Q$. Compound $P$ gives a yellow precipitate when treated with $I_{2}$ and $NaOH$ but does not reduce Tollen's reagent. Compound $Q$ does not give any yellow precipitate with $I_{2}$ and $NaOH$ but gives Fehling's test. The compound $X$ is:

• A
  $Ph-C(CH_3)=CH-CH_2-CH_3$
• B
  $Ph-CH=C(CH_3)-CH_2-CH_3$
• C
  $Ph-CH=CH-CH_2-CH_2-CH_3$
• D
  $Ph-C(CH_3)=C(CH_3)_2$
