An alkene $(A)$ $C_{16}H_{16}$ on ozonolysis gives only one product $(B)$ $C_8H_8O$. $(B)$ can also be obtained by the hydrolysis of the product obtained from the reaction between cyanobenzene and $CH_3MgBr$. $(A)$ shows geometrical isomerism and decolourises $Br_2$ water. $(B)$ on treatment with $SeO_2$ produces $(C)$. Which statement is not correct about $(C)$?

• A
  On treatment with $NaBH_4$ it will produce a diol.
• B
  On treatment with $OH^{-}$ (conc.) followed by acidification it produces an optically active acid.
• C
  It gives Tollen's test.
• D
  It can take part in aldol condensation.
