D. Penile urethra

Answer

To solve the question regarding the part of the urethra that is surrounded by corpus spongiosum, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the specific part of the urethra that is surrounded by the corpus spongiosum.

2. **Identify the Structures**: Recognize that the corpus spongiosum is a spongy erectile tissue that runs along the length of the penis and surrounds the urethra.

3. **Know the Parts of the Urethra**: The urethra has several segments:
- Prostatic urethra
- Membranous urethra
- Penile (or spongy) urethra
- Urinary urethra

4. **Locate the Corpus Spongiosum**: The corpus spongiosum surrounds the urethra in the penile region. This is crucial because it provides the necessary support and prevents the urethra from collapsing during erection.

5. **Determine the Correct Answer**: Since the corpus spongiosum is present throughout the penis and directly surrounds the urethra in this area, the part of the urethra that is surrounded by the corpus spongiosum is the penile urethra.

6. **Final Answer**: Therefore, the correct answer is **penile urethra**.
