cilia
D none of the above are NOT functions of the epithelium, ie they all are. But its a badly worded question.
The specialization at apical surfaces of epithelium includes microvilli, cilia, or stereocilia, which are involved in functions such as absorption, secretion, or movement of substances across the epithelial layer. These structures increase the surface area for better absorption and provide a way for the epithelial cells to interact with their environment.
The cilia on the surface of the ciliated epithelial cell are used for sweeping or moving mucus and debris along the cell's surface. These hair-like structures beat in a coordinated manner to facilitate the movement of particles.
Geology
The movement of materials inside a cell is called intracellular transport, which includes processes like endocytosis, exocytosis, and vesicle transport. In multicellular organisms, the movement of materials between cells and tissues is facilitated by processes like diffusion, active transport, and bulk flow through specialized structures like blood vessels and lymphatics.

microvilli, tremendously increase exposed surface area in epithelial tissue.
It means that the cells that line structures were found, but they were not the type found in the kidneys.

These structures increase the surface area for better absorption and provide a way for the epithelial cells to interact with their environment.
Epithelial tissue is composed of tightly packed cells that line organs and serve as barriers to protect against injury, infection, and absorption of nutrients. It is avascular, meaning it lacks blood vessels, and is classified based on its shape (squamous, cuboidal, columnar) and number of cell layers (simple, stratified). Epithelial tissue can also contain specialized structures like cilia or microvilli to assist in functions such as movement or absorption.
Cilia are slender, hair-like structures found on the surface of cells that aid in movement and the transportation of materials. They can be found in various organisms, including humans, and serve functions such as facilitating the movement of mucus in the respiratory tract.
The epithelial tissue acts most similarly to skin tissue in multicellular organisms. It functions as a protective barrier against infection, regulates the movement of materials, and provides sensory information.
Epithelial cells exhibit modifications that adapt them for functions like protection, absorption, or filtration. These modifications can include features such as cilia for movement, microvilli for increased surface area, or tight junctions for barrier function.

Geology
The functions are it provides shape and support, enables movement, protects organs, produces blood cells, and stores minerals and other materials.
The cilia are tiny, hair-like structures found on the surfaces of cells. They are involved in various functions such as movement or sensing the environment.
