Final answer:
The ectoderm forms the epidermis and nervous system, the mesoderm gives rise to bones, muscles, and certain organs, and the endoderm develops into the internal organs like the lungs and pancreas.
Step-by-step explanation:
In human development, the three germ layers each give rise to different parts of the body's tissue and organs. The ectoderm differentiates into the body's outer layers, including the epidermis, and parts of the nervous system, such as the brain and spinal cord. The mesoderm gives rise to structures like bones, muscles, the heart, and kidneys. Lastly, the endoderm contributes to the development of many internal organs, such as the pancreas, lungs, and parts of the digestive system.
Therefore, the correct statement evaluating the development of these germ layers is: The ectoderm will become the outer skin and parts of the nervous system. The endoderm will differentiate into many internal organs like the pancreas and lungs. The mesoderm will differentiate into the bones, muscles, and kidneys.
