You are presented with the question "Force acting against motion causes what?" and the following answer choices: 
- Object to lose energy.
 - depress neuronal excitability
 - body temperature reduces
 - kinetic energy
 - heat production
 - heat is produced
 - heat the body
 - a lot of human deaths

Now knowing that friction causes an object to lose energy and byproducts of friction Friction is a force acting against motion, choose the best answer.
