Use duckduckgo.com to look up each term. I can tell you right now, it's not diaphragm!
Nose would be the correct answer.
All the others, as you'll see by Googling, are just other components that do not filter air. It is also somewhat obvious since the nose (other than the mouth) is the only input area of air, so it must be the answer.
As air goes through the nostrils, the nose-hairs filter it so it doesn't cause any problems inside the lungs.
