Which term describes the nostrils?

Explanation:
Nares are the two external openings of the nose, the nostrils. This term is used for the nostrils collectively, which is why it fits the plural “nostrils” in the question. Naris would refer to a single nostril, so it’s not as accurate for the pair. The internal space behind them is the nasal cavity, not the openings themselves, and oris relates to the mouth. So the best term for the nostrils is nares.
