Explanation / Answer

ANS) The external nose functions in:

A) Modifying speech vibrations.

The reason to my answer is:

external nose helps in changing discourse vibrations as they go through the expansive, empty resounding chambers. By far most of discourse sounds are delivered by making a flood of air which streams from the lungs through the mouth or nose. We utilize this flood of air to shape particular sounds with our vocal folds or by changing the shape of our mouths. This is also the reason why we can't speak well by closed or blocked nose.
