Best answer

Answer: 1. Epinephrine

Key idea: Hormones made from amino acids (amines, peptides, proteins) differ from steroid hormones made from cholesterol.

Epinephrine (adrenaline) is derived from the amino acid tyrosine, so it is an amino acid derivative.
Estradiol and estriol are estrogens, and ecdysone is the insect moulting hormone. All three are steroids.

So the answer is option 1.
