Solution:
Book lungs are the respiratory organs found in arachnids such as scorpions and spiders. Thus, A matches with II.
Book gills are the respiratory organs of marine arthropods like Limulus (king crab). Thus, B matches with III.
Internal gills are the primary respiratory organs in fishes, such as Harpadon (Bombay duck). Thus, C matches with IV.
External gills are present in the larval stages of amphibians, such as the Salamander's tadpole. Thus, D matches with I.
The correct matching is A-II, B-III, C-IV, D-I.
