Which of the following statements about joints is true?
a.
fixed joints have the greatest range of motion.
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

The joint is place where two bones join to assist in movement of an individual.

Further Explanation:

The portion at which two or three bones articulates are called joints. They are mainly responsible for the stability and movement of bones. The joints are classified into:

The bones of fibrous joints are connected to bones through fibrous connective tissue. They have no space, or cavity present in between the bones. So, fibrous joints do not allow movement.

Synovial joints have a vacant space in between the adjacent bones. The space is known as synovial cavity which is filled by the synovial fluid. The fluid provides lubrication in the joints, greater movement and reduces the friction between bones.

Cartilaginous joints are connected to bones through cartilage. There are two kinds of cartilaginous joints that are synchondroses and symphyses. In synchondrosis, bones are joined by hyaline cartilage. In symphyses, the bones are connected through fibrocartillage, and hyaline cartilage covers bone ends. They only allow the minor movement of bones.
