If the question is "is rib cage part of respiratory or part of skeletal system" what would be the answer

It is part of the skeletal system, because it is the bone that protects the respiratory system, AKA the lungs. I hope this helps you!

The rib cage is bone and all of the bones in your body make a skeleton, so the rib cage is apart of the skeletal system. Also, the respiratory system is your lungs, esophagus, mouth, and nose. It is the system in which does the act of exchanging carbon dioxide for oxygen. Hopes I helped!

Cand d are correct because the rest are just showing your mistakes and you don’t want people who are reading a summary you wrote to see all the mistakes you made.
