Solution
The correct option is C Thyroid
- Metamorphosis is a profound change of form during development from larva to adult animals.
- The process of metamorphosis is essentially under hormonal control. Hormones from the hypothalamus (e.g. TSH or thyroid-stimulating hormone) and the thyroid gland regulate the process of metamorphosis.
- Thyroxine hormone secreted by the thyroid gland affects the tissues directly, causing the degeneration and necrosis of some cells and stimulating the growth and differentiation of others.
- Thus, thyroid glands play a key role in the metamorphosis of a frog.
Therefore, the correct answer is option B.
