Correct Answer is B

Explanation

Choice A rationale

This statement is incorrect because an antagonist medication changes the effects of normal cellular functions by blocking receptors.

Choice B rationale

An antagonist medication binds to receptors and blocks the usual receptor activity, preventing the normal action of the endogenous substance.

Choice C rationale

This statement describes an agonist medication, which binds to receptors and increases the effects of normal cellular functions.

Choice D rationale

This statement is incorrect because an antagonist medication does not both increase and decrease the effects on normal cellular functions; it primarily blocks receptor activity.
