Malpighian tubule are lined by

Options

A. Glandular epithelium with ciliated cells
B. Simple epithelium and non-ciliated cells
C. Cutinised epithelium
D. Simple squamous epithelium

Explanation

### Step-by-Step Solution:

1. **Understanding Malpighian Tubules**: Malpighian tubules are excretory structures found in insects, including cockroaches. They play a crucial role in the excretion of nitrogenous waste.

2. **Location in the Alimentary Canal**: These tubules are located at the junction of the midgut and hindgut of the cockroach's alimentary canal.

3. **Structure of Malpighian Tubules**: Each Malpighian tubule is a fine, thread-like structure. They are typically 100 to 150 in number in a cockroach.

4. **Lining of Malpighian Tubules**: The inner lining of the Malpighian tubules is made up of a specific type of epithelial tissue.

5. **Identifying the Epithelial Tissue**: The epithelial tissue lining the Malpighian tubules is ciliated and glandular. This means it has tiny hair-like structures (cilia) that help in the movement of substances and also contains glands that assist in the excretion process.

6. **Function of Cilia**: The cilia present on the epithelial cells help in the one-directional flow of excretory products from the hemolymph (the insect's blood) into the tubules and eventually to the ileum for elimination.

7. **Conclusion**: Therefore, the Malpighian tubules are lined by ciliated glandular epithelium.

### Final Answer:
Malpighian tubules are lined by **ciliated glandular epithelium**.
