Which of the following lists components of the skeletal system?

The components of the skeletal system include bones, cartilages, and ligaments, making this option the correct choice. Bones are the primary structural elements of the skeletal system, providing support, protecting vital organs, and facilitating movement in conjunction with muscles. Cartilages serve as flexible connective tissues that provide cushioning at joints and contribute to the shape of structures like the nose and ears. Ligaments are fibrous connective tissues that connect bones to other bones at joints, playing a crucial role in stabilizing the skeletal framework.

Other options focus on different systems or components of the body. For instance, skin, hair, and nails relate to the integumentary system, which protects the body and regulates temperature. The heart, lungs, and vessels are all part of the cardiovascular and respiratory systems, essential for circulation and respiration. Muscles, tendons, and joints are associated with the muscular system, working together to enable movement and support body posture, but they do not directly encompass the skeletal system in the same way that bones, cartilages, and ligaments do.
