Answer:
A. Food inspection
Step-by-step explanation:
The public health department's purpose is to "protect and improve the health of people and their communities". By this definition, we can get a better idea of what the question is asking us. Furthermore, it is also true that the FDA (Food and Drug Administration) works to distribute and evaluate the cleanliness and safety of food and medicines around the country.
The answer cannot be B, because it involves an individual examining themselves, which is not involving public health
And the answer isn't C because they are not healthcare professionals. That would be a job for the hospital.
And it is not D, because they are definitely not allowed to perform surgeries on routine inspections.
Another reason why it is not any of these is that they are all healthcare-related. You would go see a healthcare professional for these options, not the FDA!
So the correct answer is A. Food inspection. Hope this helped!
