The correct option is A Ammonotelic
Aquatic animals such as bony fishes, aquatic invertebrates, and amphibians excrete ammonia because it is easily eliminated in the water. Ammonia is easily soluble in water. Thus aquatic animals are ammonotelic. Mammals are ureotelic i.e., excrete urea while reptiles and birds are uricotelic ie excrete uric acid. Thus, the correct answer is option B.
