The correct answer is Ligaments.

- Ligaments are strong, fibrous connective tissues that connect one bone to another at a joint.
- Their primary function is to provide stability to the joint by limiting excessive or abnormal movements, thereby preventing dislocations and injuries.
- Unlike tendons, which connect muscles to bones and facilitate movement, ligaments specifically serve to stabilize and support joints.

To clarify the other options:
- Tendons connect muscles to bones and are responsible for transmitting the force generated by muscles to move bones.
- Fascia is a band or sheet of connective tissue that surrounds muscles, groups of muscles, blood vessels, and nerves, providing support and reducing friction.
- Cartilage is a flexible connective tissue that cushions joints and provides a smooth surface for articulation but does not connect bones directly.

Understanding these distinctions is crucial in anatomy and clinical medicine for diagnosing joint injuries and planning appropriate treatments.
