Answer: (A)

Verified step by step guidance

1. Understand the autonomic nervous system (ANS) and its divisions: The ANS is responsible for involuntary physiological functions and is divided into the sympathetic, parasympathetic, and enteric divisions. The somatic division, on the other hand, controls voluntary movements.
2. Learn the role of the sympathetic division: The sympathetic division is often referred to as the 'fight or flight' system. It prepares the body for action, including increasing heart rate, dilating pupils, and stimulating processes like ejaculation.
3. Contrast the parasympathetic division: The parasympathetic division is known as the 'rest and digest' system. It promotes relaxation and processes like digestion, but it does not control ejaculation.
4. Understand the enteric division: The enteric division is primarily involved in gastrointestinal functions and does not play a role in ejaculation.
5. Clarify the somatic division: The somatic division controls voluntary muscle movements and is not part of the autonomic nervous system. It does not regulate ejaculation, which is an involuntary process controlled by the sympathetic division.
