Why are hormones called chemical messengers?
Answer and explanation
Correct answer: Because they carry messages chemically to target organs
Hormones are chemical substances released by endocrine glands into the blood. The circulation carries them to particular target cells or organs, where they bind to receptors and change the activity of those targets. Because they transmit regulatory information chemically rather than through nerve impulses, they are called chemical messengers. Thus option A is correct; the other options misrepresent their nature.
