Explanation:

Cilia are hair-like structures that help in movement and are found on the surface of some cells.

• They are formed from basal bodies, which originate from centrioles.
• Cell membrane (B) covers the cell but does not produce cilia.
• Cytoplasm (D) is the fluid inside the cell but does not directly produce cilia.

Since cilia originate from centrioles, option C is correct.
