Langerhans cells', 'role': 'user'}, {'content': 'Answer: D \nExplanation: Langerhans cells are antigen presenting cells located in the skin and migrate towards lymphoid tissue. In abnormal conditions\xa0like histiocytosis, there they invade the lung in large numbers. Kulchitsky cells are the neuro-endocrine cells found in the lining\xa0epithelium of lung and belong to the APUD system. Clara cells are the non-ciliated cuboidal/columnar cells in the wall of terminal /\xa0respiratory bronchioles. They function as stem cells for repair of epithelium and also secrete the surfactant lipoproteins like the type-II pneumocytes. Brush cells have microvilli at their surface and are innervated by nerve fibers, and function as receptor cells.', 'role': 'assistant'}]
