What is the relationship between temperature and aggression?

A) Increases in temperature reduce the rate of violent crime because people are lethargic and stay inside in front of their fans or air conditioners.
B) Decreases in temperature increase the rate of violent crime because people are less observant during colder months and there are fewer witnesses on the street to stop a crime in progress.
C) Increases in temperature increase the rate of violent crime because warm temperatures make people irritable and more likely to lose their temper when provoked or frustrated.
D) There is no clear relationship between temperature and aggressive behaviours.
