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.

For this reason, we can say that the letter A shows a problem that can best be solved by community action.
