Verified step by step guidance

Step 1: Understand the context of the question. The problem is asking about the structural types of joints, which refers to how bones are connected and the material that binds them together, not their functional classification or movement types.
Step 2: Recall the three structural types of joints in the human body. These are: Fibrous joints (connected by dense connective tissue), Cartilaginous joints (connected by cartilage), and Synovial joints (characterized by a fluid-filled joint cavity).
Step 3: Differentiate between structural and functional classifications of joints. Functional classifications (synarthrosis, amphiarthrosis, diarthrosis) describe the degree of movement allowed by the joint, while structural classifications describe the physical connection between bones.
Step 4: Eliminate incorrect options. 'Hinge, ball-and-socket, pivot' refers to types of synovial joints based on movement, not structural types. 'Elastic, rigid, flexible' is not a recognized classification in anatomy. 'Synarthrosis, amphiarthrosis, diarthrosis' refers to functional classifications, not structural types.
Step 5: Confirm that the correct answer is 'Fibrous, cartilaginous, synovial,' as these are the three structural types of joints in the human body.
