You are presented with the question "what is a form of diffusion?" and the following answer choices: 
- Move to another area
 - vesicle transport
 - By wind and rain
 - through water
 - Soil movement
 - by making heat
 - Evaporation
 - Veins and arteries.

Now knowing that vesicle transport requires energy, so it is also a form of active transport and active transport is yet another form of diffusion, choose the best answer.
