The major product expected when Phthalamide is treated with $NaOH$ is:

An organic compound $[A]$,molecular formula $C_{10}H_{20}O_2$,was hydrolyzed with dilute sulphuric acid to give a carboxylic acid $[B]$ and an alcohol $[C]$. Oxidation of $[C]$ with $CrO_3-H_2SO_4$ produced $[B]$. Which of the following structures are not possible for $[A]$?
