B Correct answer
Explanation

The parasympathetic nervous system (rest and digest) stimulates digestive activities via the vagus nerve. It increases GI secretions and enhances peristalsis after food ingestion. The sympathetic nervous system (fight or flight) would inhibit digestion, while the central nervous system and thyroid membrane are not directly responsible for digestive regulation.
