Final answer:

The answer is D. hadrosaurids. Few dinosaurs showed any signs of being aquatic, but some evidence suggests hadrosaurids may have been semi-aquatic.

Step-by-step explanation:

The correct answer is D. hadrosaurids. Other than some hadrosaurids, no compelling argument can be presented that any dinosaur was aquatic. Dinosaurs, such as the massive sauropods, the bird-hipped ornithischia, and the carnivorous theropods that gave rise to birds, were primarily land dwellers. Fossil evidence such as nests and eggs suggest they laid their eggs on land. In contrast, truly aquatic reptiles, like Mesosaurs, which lived during the early Mesozoic Era, showed adaptations for swimming and lived in aquatic habitats such as lakes and coastal bays.
