The correct answer is option D - ciliated epithelium.

The inner surface of the bronchi, bronchioles, and fallopian tubes is lined by ciliated epithelium. Let's break down this answer and explain it in detail.

1. What is epithelium?
Epithelium is one of the four primary types of animal tissue, along with connective tissue, muscle tissue, and nervous tissue. It forms the outer layer of skin, lines the body cavities, and covers the internal organs. Epithelial tissue functions to protect, secrete, absorb, and transport substances.

2. Types of epithelial cells:
There are different types of epithelial cells based on their shape and arrangement. The common types include squamous, cuboidal, and columnar epithelium.

3. Ciliated epithelium:
Ciliated epithelium is a type of columnar epithelium that possesses tiny hair-like structures called cilia on its surface. These cilia beat in coordinated waves, creating a sweeping motion that helps move mucus, dust, and other particles out of the respiratory tract and fallopian tubes.

4. Function in the respiratory system:
In the respiratory system, the ciliated epithelium lining the bronchi and bronchioles helps to remove foreign particles and pathogens from the airways. The cilia move in a coordinated manner, propelling mucus and trapped particles upward towards the throat, where they can be coughed out or swallowed.

5. Function in the fallopian tubes:
In the fallopian tubes, the ciliated epithelium plays a crucial role in moving the egg from the ovary towards the uterus. The cilia create a current that helps propel the egg along the fallopian tube, aiding in fertilization and transportation.

In summary, the inner surface of the bronchi, bronchioles, and fallopian tubes is lined by ciliated epithelium. This type of epithelium with its cilia helps in the movement of mucus, particles, and eggs in the respective organs, contributing to their proper functioning.
