A. There has been a sudden increase in the crime rate in Hannah's neighborhood, and she feels unsafe.
Explanation:
Letter B and letter C are personal and individual problems and cannot be solved by the community, but only by the person involved. However, increasing crime in a neighborhood is a problem that affects the entire community, and while it is the state's duty to address it, the population can adopt tactics and set guidelines to reduce the incidence of traffic in their neighborhood. For this reason, we can say that the letter A shows a problem that can best be solved by community action.
