Answer #1

Answer :- D . increased gastrointestinal activity.

Explanation :- Parasympathetic nervous system is antagonistic to the sympathetic nervous system .

Neurotransmitters in case of sympathetic:Acetylcholine ( small amount ) and  Epinephrine

Neurotransmitter in case of parasympathetic:Acetylcholine
parasymapathetic nervous system stimulate gastric secretion and improve digestion , increases salivation , decreses heart rate while sympathetic nervous system decreses salivation , increases heart rate and blood pressure , increases secretion of adrenal medulla and increases respiratory rate ...
