(D) The air passage in humans follows a specific anatomical sequence:$1$. External nostrils: Air enters through these openings.$2$. Nasal passage: Leads from the nostrils to the internal nares.$3$. Pharynx: The common passage for air and food.$4$. Larynx: The voice box,which leads to the trachea.$5$. Trachea: $A$ straight tube extending up to the mid-thoracic cavity.$6$. Bronchi: The trachea divides into right and left primary bronchi.$7$. Bronchioles: Bronchi undergo repeated divisions to form secondary,tertiary bronchi,and finally bronchioles.$8$. Alveoli: The terminal bronchioles end in thin,irregular-walled,vascularized,bag-like structures called alveoli,where gas exchange occurs.Therefore,the correct sequence is: External nostril $\rightarrow$ Nasal passage $\rightarrow$ Internal nostril $\rightarrow$ Pharynx $\rightarrow$ Larynx $\rightarrow$ Trachea $\rightarrow$ Bronchi $\rightarrow$ Bronchioles $\rightarrow$ Alveoli.
