Hydration reactions often involve the addition of water molecules to stabilize reactive intermediates




The reaction involves hydration followed by rearrangement:
• The given structure undergoes hydration, leading to the addition of hydroxyl (−OH) groups.
• Hydrogen bonding stabilizes the structure, resulting in the product OH−O−OH
The correct option is(D):
