Answer: a plan for garbage disposal services for residents
Step-by-step explanation:
A Special-purpose district is a political subdivision that is created by the legislative authority that the district is to be in.
The reason such a district is created usually has to do with service provision. It can be either to provide services to the district, to upgrade the services offered or to better finance the services offered.
A new garbage disposal service therefore qualifies for this so option A is correct because a special purpose district may need to be created to provide the garbage disposal.
