Explanation:

The cribriform plates of the ethmoid bone have olfactory foramina through which olfactory nerves pass for the sense of smell. Ethmoidal sinuses are air - filled cavities, the styloid process is not related to the ethmoid bone's olfactory function, and the perpendicular plate is mainly a structural part not associated with olfactory nerve passage.

Answer:

A. Cribriform plates
