Answer 1

(d) Nostrils→pharynx→larynx→trachea→alveoli

The air for respiration is drawn into our body through the nostrils, it then goes into the nasal passage. From there, air enters into pharynx, larynx, then into the trachea, bronchi, lungs and finally to the alveoli where gaseous exchange takes place.
