D. Prostatic, bulbourethral and glans.

Answer

To answer the question regarding the various parts of the male urethra, we can break it down step by step:

### Step-by-Step Solution:

1. **Understanding the Male Urethra**: The male urethra is a fibromuscular tube that serves two primary functions: it conducts urine from the bladder and semen from the reproductive system to the outside of the body.

2. **Identifying the Parts of the Male Urethra**: The male urethra is divided into three main parts:
- **Prostatic Urethra**: This is the first part of the male urethra, which passes through the prostate gland. It is approximately 3-4 cm long and is the widest part of the urethra.
- **Membranous Urethra**: This is the second part, which is shorter (about 1-2 cm) and passes through the urogenital diaphragm. It is the narrowest part of the urethra.
- **Penile (or Spongy) Urethra**: This is the final part of the male urethra, which runs through the length of the penis. It is about 15-20 cm long and is surrounded by erectile tissue.

3. **Evaluating the Options**: Now, we can evaluate the provided options:
- **Option A**: Prostatic, Vulper urethral, and ejaculatory - This option includes "Vulper urethral," which is not a recognized part of the male urethra.
- **Option B**: Prostatic, Membranous, and Penile - This option correctly lists the three parts of the male urethra.
- **Option C**: Corporal Cavernosa and Corporal Spongiosum - These are erectile tissues, not parts of the urethra.
- **Option D**: Prostatic, Vulper urethra, and glands - Again, "Vulper urethra" is not a recognized term.

4. **Conclusion**: Based on the analysis, the correct answer is **Option B: Prostatic, Membranous, and Penile**.

### Final Answer:
**Option B: Prostatic, Membranous, and Penile.**
