Local governments provide different services. under which category of services do firefighters fall?

Public safety
 Protecting the public against fire, explosion etc is the primary duty. It is a public matter because even though fires are often started privately, they can spread and damage property and endanger lives of the surrounding community. Very often they get out of control much faster than a private party would be able to put them out.

Sorry sir you did not give us the graph i typically but i'm very confused my conclusion is you're missing valuable information in the question
