**Core Concept**
Epispadias is a rare congenital anomaly characterized by the urethra opening on the dorsum (back side) of the penis in males or between the clitoris and labia in females. It is often associated with other genitourinary abnormalities, such as bladder exstrophy.

**Why the Correct Answer is Right**
Epispadias occurs due to incomplete fusion of the urethral folds during embryonic development. In males, this results in an abnormal urethral opening on the dorsum of the penis, often accompanied by a bifid (split) penis. This condition is often linked to bladder exstrophy, a condition where the bladder and abdominal wall do not properly close during fetal development.

**Why Each Wrong Option is Incorrect**
* **Option A:** This is incorrect as epispadias is not typically associated with hypospadias, which is a different congenital anomaly characterized by the urethra opening on the underside of the penis.
* **Option B:** This is incorrect as epispadias is not associated with a normal urethral opening.
* **Option C:** This is incorrect as epispadias is not typically associated with a duplicated urethra.

**Clinical Pearl / High-Yield Fact**
Epispadias is often associated with other genitourinary abnormalities, such as bladder exstrophy, and may require surgical correction to restore normal urinary function and genital anatomy.

**Correct Answer: C. Bladder exstrophy.**
