An organic compound [A], molecular formula ${\mathrm{C}}_{10}{\mathrm{H}}_{20}{\mathrm{O}}_2$ was hydrolyzed with dilute sulphuric acid to given a carboxylic acid [B] and an alcohol [C]. Oxidation of [C] with ${\mathrm{CrO}}_3-{\mathrm{H}}_2{\mathrm{SO}}_4$ produced [B]. Which of the following structures are not possible for $\left[\mathrm{A}\right]$

• A

  
• Correct answer
  B

  
• C

  ${\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{COOCH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_3$
• D

  ${\left({\mathrm{CH}}_3\right)}_3-\mathrm{C}-{\mathrm{COOCH}}_2\mathrm{C}{\left({\mathrm{CH}}_3\right)}_3$

Hence, the correct answer is option: 'B'.
