**Core Concept**
Hypospadias is a congenital anomaly of the male urethra, where the urethral meatus is located on the underside of the penis. It occurs due to incomplete closure of the urethral folds during embryonic development.

**Why the Correct Answer is Right**
The most common type of hypospadias is glandular hypospadias, where the urethral meatus is located on the glans penis. This occurs due to incomplete closure of the urethral folds, resulting in a urethral meatus on the underside of the glans. The glans is the enlarged, sensitive head of the penis, which contains the opening of the urethra in normal males.

**Why Each Wrong Option is Incorrect**
* **Option A:** Penile hypospadias is a less common type, where the urethral meatus is located on the shaft of the penis, rather than the glans.
* **Option B:** Perineal hypospadias is a rare type, where the urethral meatus is located on the perineum, the area between the scrotum and anus.
* **Option C:** Epispadias is a different congenital anomaly, where the urethral meatus is located on the top of the penis, rather than the underside.

**Clinical Pearl / High-Yield Fact**
Hypospadias is the most common congenital anomaly of the male urethra, occurring in approximately 1 in 200 male births.

**Correct Answer: A. Glandular hypospadias**
