Which nerve is responsible for the sneezing reflex?

Correct answer is C) Trigeminal nerve. The trigeminal nerve, also known as the fifth cranial nerve, is responsible for the sneezing reflex. It is the main nerve of the face and head, and it carries sensory information—including irritation in the nasal mucosa that can lead to a sneeze. When this nerve detects irritants, it sends signals to the brainstem, which then initiates the sneeze reflex to expel the irritants from the nasal cavity.
