Final answer:
Local governments are responsible for waste disposal, which includes the management of trash and recycling within local jurisdiction.
Step-by-step explanation:
The service provided by local governments among the options given is waste disposal. This refers to the management of trash and recyclables, which is a key responsibility of local, rather than state or national, governments.
Moreover, municipal governments are known for their role in maintaining city facilities, providing law enforcement, public transportation, and fire protection, among others. However, services like the national guard and state health plans are typically managed at the state or national levels rather than the local level.
