The correct answer is C.
Municipal services, also called city services, are services offered by the city government to its citizens. These services are done in exchange for taxes paid by the citizens to the government.
The most common and basic municipal services are: sanitation (sewer and refuse), water administration, schools, police, fire department, libraries and many more.
When a municipality collects trash it is providing citizens with a service agreed upon earlier on. The citizen determine how often they want their trash to be collected and pay the appropriate amount of money for the service.
