Pancreatic duct - squamous epithelium
Moist surface of buccal cavity - glandular epithelium
Tubular parts of nephrons - cuboidal epithelium
Inner lining of salivary ducts - ciliated epithelium
The proximal convoluted tubule, which is the longest part of the renal tubule has simple tall cuboidal epithelium, with a brush border (microvilli). The epithelial cells in the distal convoluted tubule are cuboidal, with very few microvilli. The inner lining of salivary ducts has stratified columnar epithelia. A stratified squamous non-keratinized epithelium lines the oral surface. Bronchioles are lined by simple cuboidal epithelium. So, the correct answer is option C.
