Final answer:
The correct examples of solid viscera, which maintain a consistent shape, are B) Kidneys and pancreas.
Step-by-step explanation:
The solid viscera are the organs that maintain their shape regardless of the surrounding conditions. These organs, unlike hollow viscera like the intestines or stomach, do not change shape significantly or contain large cavities. Based on the options provided in the question, the correct examples of solid viscera would be B) Kidneys and pancreas. This is because both the kidneys and the pancreas maintain a consistent shape and do not have large, variable cavities like the organs in option A) Liver and stomach or option C) Lungs and bladder. Furthermore, option D) Small and large intestine are not considered solid viscera as they are examples of hollow viscera.
