Answer: (D)

Verified step by step guidance

1. Begin by understanding the term 'synostosis'. Synostosis refers to a type of joint where two bones have fused together, resulting in a single bony structure.
2. Recognize that synostosis is a permanent fusion of bones, which distinguishes it from other types of joints that allow movement or are connected by cartilage or fibrous tissue.
3. Consider the characteristics of different types of joints: Cartilaginous joints are connected by cartilage, fibrous joints are connected by fibrous tissue, and synovial joints are characterized by a fluid-filled cavity that allows movement.
4. Identify that a synostosis does not fit the description of cartilaginous, fibrous, or synovial joints because it involves the fusion of bones into a single bony structure.
5. Conclude that a synostosis is best described as a 'bony joint', which is a joint where the bones have fused together, eliminating any movement between them.
