A
(i) Necturus (ii) Pila (iii) Millipede (iv)Toad
💡 Explanation:
Necturus (Mud puppy, Amphibia) possesses three pairs of external gills. Pila (Apple snail, Mollusca) respires by means of gills (ctenidium) in water and by a pulmonary sac on land. Millipedes (Arthropoda) respire by tracheae (tracheal respiration) and toads (Amphibia) exhibit buccopharyngeal respiration.
So, the correct answer is (D).
