Options

A. 15 cm
B. 10 cm
C. 4 cm
D. 2 cm

Answer

### Step-by-Step Solution:

1. **Understanding Urethra Anatomy**: The urethra is a tube that carries urine from the bladder to the outside of the body. In humans, the urethra differs in length and structure between males and females.

2. **Comparing Male and Female Urethra**: The male urethra is significantly longer than the female urethra. This difference is primarily due to anatomical structures, particularly the male reproductive system.

3. **Length of Male Urethra**: The male urethra is approximately 20 cm long. It is divided into three parts:
- **Prostatic Urethra**: This is the portion that passes through the prostate gland and is about 2-3 cm long.
- **Membranous Urethra**: This is the shortest segment but is the longest part of the male urethra.
- **Spongy Urethra**: This part runs through the penis.

4. **Length of Female Urethra**: In contrast, the female urethra is much shorter, measuring about 4 cm in length. This shorter length is due to the absence of a penis and the proximity of the urethra to the bladder and external genitalia.

5. **Conclusion**: Therefore, the length of the female urethra is approximately 4 cm.

### Final Answer:
The length of the female urethra is approximately **4 cm**.
