In human males urethra has
(a) transitional epithelium
(b) Pseudostratified non-ciliated columnar epithelium
(c) non - keratinised stratified squamous epithelium
(d) all of these

Options

A. transitional epithelium
B. Pseudostratified non-ciliated columnar epithelium
C. non - keratinised stratified squamous epithelium
D. all of these

Answer

To solve the question regarding the type of epithelium found in the human male urethra, we will analyze each option provided:

### Step-by-Step Solution:

1. **Understanding the Urethra**: The urethra in human males is part of the excretory system and serves the function of transporting urine from the bladder to the outside of the body. It is important for the urethra to have an appropriate type of epithelium that can accommodate changes in volume as urine is stored and expelled.

2. **Analyzing Option (a) Transitional Epithelium**: Transitional epithelium is specialized to stretch and is typically found in areas that need to expand, such as the bladder and urethra. This type of epithelium allows the urethra to accommodate varying volumes of urine, making it a suitable choice for the male urethra.

3. **Analyzing Option (b) Pseudostratified Non-Ciliated Columnar Epithelium**: This type of epithelium is primarily found in the respiratory tract and in the male reproductive system, particularly in the vas deferens and prostate gland. It is not the primary type of epithelium found in the urethra.

4. **Analyzing Option (c) Non-Keratinized Stratified Squamous Epithelium**: This epithelium is found in areas subject to abrasion, such as the oral cavity, pharynx, and esophagus. It is not characteristic of the urethra, which requires a more flexible type of epithelium.

5. **Analyzing Option (d) All of These**: Since we have established that options (b) and (c) are not correct for the urethra, this option cannot be true.

6. **Conclusion**: The only correct option is (a) Transitional Epithelium, as it is the primary type of epithelium found in the human male urethra.

### Final Answer:
(a) Transitional epithelium
