What are the suitable conditions for the following transformation?

• Correct answer
  A

  $\mathrm{KMnO}_4-\mathrm{H}_2 \mathrm{SO}_4 / \Delta$
• B

  $\mathrm{O}_3 / \mathrm{O}_2, \mathrm{Zn}+\mathrm{H}_2 \mathrm{O}$
• C

  $\mathrm{OsO}_4$
• D

  $\mathrm{Pb}(\mathrm{OAc})_4$

Solution

Thus, option (1) is correct.

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