**Core Concept**
The prostate gland receives innervation from both the sympathetic and parasympathetic nervous systems, which play crucial roles in regulating its function and maintaining urinary continence. This dual innervation allows for complex control over prostate secretions and urethral smooth muscle tone.

**Why the Correct Answer is Right**
The sympathetic nerves to the prostate originate from the hypogastric plexus, primarily from the T10-L1 spinal segments, and release norepinephrine to stimulate alpha-1 adrenergic receptors, leading to contraction of the smooth muscle in the prostate and urethra. In contrast, the parasympathetic nerves, arising from the pelvic splanchnic nerves, release acetylcholine to stimulate muscarinic receptors, resulting in relaxation of the smooth muscle and increased blood flow to the prostate. This delicate balance between sympathetic and parasympathetic control is essential for normal urinary function.

**Why Each Wrong Option is Incorrect**
**Option B:** Parasympathetic: While parasympathetic innervation does play a role in regulating prostate function, it is not the sole supplier of nerves to the prostate. Ignoring the sympathetic component oversimplifies the complex neural control of the prostate.
**Option C:** Sympathetic: Similarly, while sympathetic nerves do contribute to prostate innervation, they do not act alone. The parasympathetic component is essential for maintaining normal prostate function and urinary continence.
**Option D:** None: This option is incorrect because the prostate does indeed receive innervation from both the sympathetic and parasympathetic nervous systems.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the balance between sympathetic and parasympathetic control of the prostate can be disrupted in various conditions, such as benign prostatic hyperplasia (BPH) or prostate cancer, leading to urinary symptoms and complications.

✓ Correct Answer: A. Sympathetic + Parasympathetic
