**Core Concept**
Exstrophy of the bladder is a rare congenital anomaly characterized by the abnormal exposure of the bladder mucosa, typically associated with a triad of bladder exstrophy, epispadias, and umbilical abnormalities. This condition arises due to the failure of the cloacal plate to close during embryonic development.

**Why the Correct Answer is Right**
The correct answer is related to the characteristic features of exstrophy of the bladder. The condition is often associated with a wide range of abnormalities, including:

* Bladder exstrophy: The bladder mucosa is exposed through a defect in the abdominal wall, often accompanied by a wide, flat, and shallow bladder.
* Epispadias: A urethral opening on the dorsum (upper surface) of the penis in males or a short, wide urethra in females.
* Umbilical abnormalities: An abnormal umbilicus, often with a wide, flat, or cleft-like appearance.
* Inguinal hernias: Due to the weakness in the abdominal wall.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is likely incorrect as it may not be a feature of exstrophy of the bladder.
* **Option B:** This option could be a feature of exstrophy of the bladder, as it is often associated with umbilical abnormalities.
* **Option C:** This option is likely incorrect as it may not be a feature of exstrophy of the bladder.
* **Option D:** This option is likely incorrect as it may not be a feature of exstrophy of the bladder.

**Clinical Pearl / High-Yield Fact**
In cases of exstrophy of the bladder, patients often require surgical repair to correct the bladder exstrophy, epispadias, and umbilical abnormalities. Early surgical intervention is crucial to prevent complications and improve long-term outcomes.

**Correct Answer: D.**
