Correct answer: A. Visceral mesoderm
- A. Visceral mesoderm
- B. Parietal mesoderm

Explanation
The visceral mesoderm is a layer of the mesoderm in embryonic development that surrounds and supports the internal organs or viscera, including the heart, lungs, and digestive organs. It plays a vital role in the formation and development of these organs during embryogenesis, providing structural and functional support to ensure proper organ function.
