B. `{:("Characteristics","Examples"),("Fluid filled between two joints, provides cushion","Shull bones"):}`
C. `{:("Characteristics","Examples"),("Fluid filled synovial cavity between two bones","Joint between atlas and axis"):}`
D. `{:("Characteristics","Examples"),("Lymph filled between two bones, limited movement","Gliding joint between carpals"):}`

Answer

C

Explanation

Joint between atlas and axis is pivot joint, which is an example of synovial joint charecterised by the presence of a fluid -filled synovial cavity between the articulating surface of the two bones. Knee joint (hinge joint) is a synovial cavity between the articulating surfaces of the two bones.
Fluid cartilage between two bones having limited movements is slightly movable joint. In freely movable joints fluid filled between two joints provides cushion. In gliding joint, the articulating bones can slide upon one another.
