A Correct answer
Explanation

Horses are obligate nasal breathers - they cannot breathe through their mouths and must inhale exclusively through their nostrils. This anatomical adaptation prevents them from swallowing food while breathing, reducing choking risk. Other animals like dogs, cats, and crocodiles can all breathe through their mouths when needed.
