Answer & Solution
Correct answer: C. tracheal tubes piping air to tissues
Insects have a tracheal system — air enters through spiracles and travels through branching tracheae and tracheoles directly to the tissues.
Gas exchange bypasses the blood entirely.
Fish have gills, amphibians use moist skin plus lungs, but insects rely on tracheae.
