Detailed explanation-1: -The sequence of air passage during inhalation is as follows: Nostrils→pharynx→larynx→trachea→alveoli.
Detailed explanation-2: -The correct order of flow of air would be: external nostrils, internal nostrils, nasal cavities, pharynx, larynx, trachea, alveoli.
Detailed explanation-3: -Final step-Therefore, out of the given options, option Nostrils → Pharynx → Larynx → Trachea → Alveoli is the most appropriate option.
