Which of the following is true regarding the structure indicated by the arrow in the joint depicted in A? a. It is composed of hyaline cartilage. b. It is classified as amphiarthrotic. c. It becomes ossified late in adult development. d. It is formed by a synovial membrane.

Considering A is a picture of a fibrous joint, a suture on the skull, the true answer is c. It becomes ossified late in adult development

Explanation:

Fibrous joints are connected by dense connective tissue, consisting mainly of collagen. A suture is a type of fibrous joint that is only found in the skull (cranial suture). This specific type becomes ossified late in adult development and it is called craniosynostosis, when the fusion is before birth.  These joints are synarthroses.
