Answer:
D
Explanation:
D, or decreased saliva production is not a reaction of the parasympathetic nervous system (PSNS) since the PSNS actually increases/causes salivation which helps you digest your food.
As a tip, I usually associate the PSNS with a state of rest/restful conditions, as opposed to the sympathetic nervous system which is the opposite and is associated with stress and high-pressure conditions (like fight or flight).
Hope this helps!! :)
