What type of epithelium lines the vagina?
- A. Ciliated epithelium.
- B. Squamous epithelium.
- C. Columnar epithelium.

Choice C, Columnar epithelium, is incorrect as columnar epithelium is typically found in areas like the intestines. Choice D, Transitional epithelium, is incorrect as this type of epithelium is found in areas like the urinary bladder.
