D Correct answer
Explanation

The autonomic nervous system (ANS) controls involuntary functions including heart rate and force (cardiac regulation) and digestive gland secretions (gastrointestinal regulation). The CNS processes information but the ANS executes these specific involuntary controls. Spinal and cranial nerves are pathways but don't regulate these functions autonomously.
