Final answer:
The correctly spelled term is 'cartilage,' which is a flexible connective tissue found in vertebrates, forming parts of the skeletal system and cartilaginous joints such as symphyses.
Step-by-step explanation:
The term that is spelled correctly is b. cartilage.
Cartilage
In vertebrates, cartilage is a type of connective tissue found in areas such as fetal bones, the ears, and intervertebral discs. Cartilage and bone are both important components of the vertebrate skeletal system. They are similar in that they are both specialized forms of connective tissue that provide support and structure to the body; however, cartilage is more flexible and less dense than bone.
Cartilaginous Joints
Cartilaginous joints are those in which bones are connected by cartilage. An example of a cartilaginous joint is a symphysis, where bones are united by fibrocartilage, such as between the vertebrae in the spine or the pubic symphysis in the pelvis.
