Solution
The correct option is D Thyroxine Metamorphism is a hormonal effect influenced by hormones. The metamorphism in frogs is under the control of thyroxine which is produced by the thyroid gland. Frogs live in water bodies with rich iodine content to produce thyroxine.The deficiency in iodine would result in a retarded growth.
