Final answer:
The coronal suture is not a type of fibrous joint.
Step-by-step explanation:
The correct answer is B. Coronal suture. The other options, A. Sydesmosis, C. Gomphosis, and D. Symphysis, are all types of fibrous joints. A sydesmosis joint is held together by a narrow band of fibrous connective tissue, a gomphosis joint is the narrow fibrous joint between a tooth and its socket in the jaw, and a symphysis joint is joined by fibrocartilage and can have a narrow or wide gap between the bones.
