The correct answer is C. The skeletal system is composed of a rigid structure of bones that support the body and make red and white blood cells.
Step-by-step explanation:
The skeletal system is one of the most important in vertebrate animals, this is composed of mainly hard structures called bones. This system plays an important role by supporting the body and giving form to it; also the skeletal system protects important organs like in the case of lungs and heart and it is responsible for the red and white blood cells that are produced in the inner structure of bones. In the case of humans, the skeletal body includes 206 different bones located along the body and without these, the movement would not be possible. According to this, the statement that best describes the skeletal system is "The skeletal system is composed of a rigid structure of bones that support the body and make red and white blood cells".
