Step-by-step explanation:
The term for a test of a drug's effect on a particular physiological system is (option A).
Pharmacodynamics is the study of how drugs interact with the body and exert their effects.
It focuses on understanding the mechanisms by which drugs produce their therapeutic and toxic effects, including the relationship between drug concentration and the response of the physiological system.
For example, if a drug is tested on a particular physiological system, such as the cardiovascular system, pharmacodynamics will investigate how the drug affects the heart rate, blood pressure, or other parameters related to cardiovascular function.
