b. most joints are joined by cartilage or connective tissue.
c. they are all very flexible.
d. they occur where two or more bones join.
please select the best answer from the choices provided.
a
b
c
d

Explanation:

• Option A: Fixed joints, like those in the skull, have no range of motion. So this option is false.
• Option B: Most joints are joined by connective tissue (like ligaments) or cartilage. But the more fundamental characteristic is their location where bones meet.
• Option C: Not all joints are very flexible. Fixed joints (e.g., skull sutures) are rigid. So this option is false.
• Option D: By definition, joints occur where two or more bones join. This is a core characteristic of joints.

Answer:

D. They occur where two or more bones join.
