• A. Cutaneous
• B. Buccopharyngeal

Answer 1

The correct option is B Buccopharyngeal

These are small opening between eyes and snout through which inhaling and exhaling occur. The nostril is situated between maxillary and vomerine teeth of the mouth cavity through which the external and internal nares are attached by a small tube-like structure.

So the correct answer is 'Buccopharyngeal'.
