Hello!
The most cohesive concluding sentence is that of option C - "If community members do not get involved with watching their own neighborhoods, they might be vulnerable to major and minor crimes."
This sentence seems to wrap up an essay far better than any of the others, and can even serve as a thesis statement.

Hope this helps!
