Solution

The correct option is C It will start metamorphosis.
The axolotl is also known as a Mexican salamander. Axolotls are unusual among amphibians in that they reach adulthood without undergoing metamorphosis. Instead of developing lungs and taking to land, the adults remain aquatic and gilled.
When sufficient amount of iodine is provided, it has profound effects on thyroid gland and results in metamorphosis. Metamorphosis yields a mature axolotl from its larval form.
