Which of the following sites is normally lined by stratified columnar epithelium?

Correct answer: A. Membranous part of the male urethra
Explanation
Stratified columnar epithelium is rare and lines the membranous and penile parts of the male urethra, large excretory ducts of salivary glands, the conjunctiva and small patches of the anal canal. The vagina is lined by non-keratinized stratified squamous epithelium, the nasal cavity by pseudostratified ciliated columnar epithelium, and collecting ducts by simple cuboidal to columnar epithelium.
