Correct Answer: A

Rationale: The correct answer is A: The parasympathetic nervous system. Gastric motility and digestion are controlled by the parasympathetic nervous system because it is responsible for rest and digest functions. When the parasympathetic nervous system is activated, it enhances digestive processes by increasing saliva production, gastric motility, and enzyme secretion. The limbic system (
B) is primarily involved in emotions and memory, not in digestive functions. The central nervous system (
C) includes the brain and spinal cord but does not directly control gastric motility and digestion. The sympathetic nervous system (
D) is responsible for the fight or flight response, which inhibits digestive functions.
Therefore, the parasympathetic nervous system is the correct choice for controlling increased gastric motility and digestion.
