Answer:
The correct answer is D. Inspecting restaurant kitchens to make sure they are clean is an example of public policy.
Step-by-step explanation:
Public policy is a concept of political science which designates the interventions of an authority invested with public power and governmental legitimacy in a specific area of society or territory.
Public policies can also be described as a set of coordinated actions, carried out by a public authority, with a view to obtaining a modification or an evolution of a given situation. The fields concerned can be of any kind: infrastructure, health, family, housing, employment, vocational training, research, public service, crisis, deficit, etcetera.
Therefore, a series of inspections of the restaurant kitchens in a given place, with the aim of contributing to the improvement of the sanitary conditions of society, is a clear example of a public policy.
