A Correct answer
Explanation

In frog growth and metamorphosis are controlled by hormones synthesized by endocrine glands near the front of the body. Neurosecretory cells in an insect's brain secrete a hormone, the prothoracicotropic hormone that activates prothoracic glands, which secrete a second hormone, usually ecdysone, that induces ecdysis. PTTH also stimulates the corpora allata, a retrocerebral organ, to produce a juvenile hormone, which prevents the development of adult characteristics during ecdysis.

So the correct answer is 'Ecdysone'.
