Correct answer

D. A: Malphigian tubules, B: Mollusca, C: Kideny, D: lung

Step-by-step solution

The excretory organs of arthropoda are: Nephridia, Coxal Glands, Green Gland, Malpighian Tubules with open circulatory system. They respire by the help of Trachae/book lungs Mollucs also have a well developed excretory system, using tubular nephridia organized as kidneys. They respire by the help of gills which are also called as ctenidia. Amphibia possess two kidneys located dorsally, in the body cavity which helps in excretion of waste. They have tails gills/gills for respiration in larval stages while lungs in a
