Correct Answer: A

Rationale: Hormones bind receptors (e.g., insulin to tyrosine kinase) on target cells, triggering responses like glucose uptake specificity defines action. Blood cells transport, not bind hormones as targets. Neurotransmitters signal neurons, not endocrine targets separate system. Enzymes process, not receive hormones. Receptor binding distinguishes endocrine signaling, critical for cellular response, unlike transport, neural, or catalytic roles.

Correct Answer: A

Rationale: Adrenal glands, atop kidneys, secrete cortisol, aldosterone, epinephrine stress and electrolyte roles. Hypothalamus is brain-based, regulatory. Pancreas is abdominal, metabolic. Thyroid is neck-located, metabolic. Adrenals' suprarenal position distinguishes them, key to adrenal-renal function, unlike brain, gut, or neck glands.
