Correct Answer: D

Rationale: The correct answer is D: Cholinergic agonist increases the activity of acetylcholine receptor sites throughout the body. A cholinergic agonist is a drug that mimics the action of acetylcholine, the neurotransmitter that binds to and activates cholinergic receptors. By increasing the activity of acetylcholine receptor sites, a cholinergic agonist enhances cholinergic neurotransmission, leading to various physiological responses.

Incorrect choices:
A: Cholinergic agonists do not affect gamma-aminobutyric acid (GAB
A) receptor sites.
B: Cholinergic agonists do not affect norepinephrine activity.
C: Cholinergic agonists do not affect dopamine receptor sites.

In summary, the correct answer is D because cholinergic agonists specifically target and enhance the activity of acetylcholine receptor sites, leading to increased cholinergic neurotransmission.
