Answer :
Final answer:
Ligaments are the structures that hold bones together in the skeletal system, hence the correct answer is A. ligaments
Explanation:
Within the skeletal system, ligaments serve a significant role. They are bands of dense, fibrous connective tissue that are essential for stabilizing joints by connecting one bone to another.
These structures ensure that the skeletal system retains its layout while permitting mobility at joints without excessive movement that might lead to injury.
Cartilage, mentioned as another option, is a flexible yet strong connective tissue found in various parts of the body.
It is known for its smooth surface at the ends of bones, aiding in the frictionless movement of joints.
The synovial membrane is another crucial component of joints, lining them and secreting synovial fluid for lubrication, but again not serving the purpose of ligaments.
