Verified step by step guidance

Step 1: Begin by identifying the primary functions of each body system listed in the problem. For example, the digestive system is responsible for breaking down food and absorbing nutrients, the muscular system facilitates movement, and the respiratory system handles gas exchange (oxygen and carbon dioxide).

Step 2: Recall the main function of the skeletal system. The skeletal system provides structural support to the body, protects vital organs (e.g., the skull protects the brain, and the rib cage protects the heart and lungs), and serves as an anchor for muscles to enable movement.

Step 3: Compare the functions of the skeletal system with the question's requirements: giving shape to the body and protecting it. The skeletal system fulfills both of these roles by forming the framework of the body and shielding internal organs.

Step 4: Eliminate the incorrect options based on their primary functions. The digestive system, muscular system, and respiratory system do not primarily give shape to or protect the body, making them unsuitable answers.

Step 5: Conclude that the correct answer is the skeletal system, as it aligns with the question's description of giving shape to and protecting the body.
