The only word out of these four which has an obvious negative connotation is C) harangue. That word means <em>to lecture somebody in an aggressive manner</em>, which is negative.
The other words have neutral connotation.
1. No running in halls so nobody falls or gets hurt
2. No interrupting the teacher while she talks so people can listen and learn in class
3. Don’t wear too exposing clothes where other can see your body
