B. Ability to move. Because all the other choices apply to all living things, but B doesn't apply to plants which are living things.

I think the reservoir ( a human,animal or non living such as soil where the infectious agent normally lives) 
secondly the mode of transmission,there are some modes of transmission that allow the pathogen to enter quickly and some that make the process slow.
and also crowding and the presence of co-infections.
i hope this helps
 
 
        
             
        
        
        
No. Plants need animals to spread their seeds. Animals also loosen the ground for seeds or other forms of plants(not everything uses seeds right?) If animals didn't eat some plants certain plants would over populate some areas, killing off the other plant life (it has a fancy name I forgot it) and last of all deceased animals sometimes provide as nutrition for other plants.
