Frogs and sea urchins were typically used to study development in classical anatomy and embryology because their eggs developed outside the mother's body, which made them easy to observe and manipulate. Additionally, their eggs were easily manipulated, allowing for experiments and observations to be conducted with greater ease. While sea urchins were not necessarily easy to breed, frogs were frequently used in breeding experiments due to their relatively simple reproductive processes. Therefore, the best choice is D, as both 1 and 2 are accurate reasons why these organisms were commonly used in developmental research.
