Which of the following health-related problems can best be solved by community action? a. there has been a sudden increase in the crime rate in hannah's neighborhood, and she feels unsafe. b. peter recently started smoking because all his friends were doing it, and he's starting to regret it. c. rebecca will be travelling abroad and needs to find out where to get the required immunizations.

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.
