Correct Answer: Hip Joint
Solution : The correct option is the Hip joint.
The hip joint is a ball-and-socket joint formed by the rounded head of the femur (thigh bone) fitting into the pelvic cup-shaped acetabulum. This type of joint allows for a variety of movements, such as flexion, extension, abduction, adduction, and rotation. Ball-and-socket joints (e.g., hip, and shoulder joints), hinge joints (e.g., elbow, and knee joints), and pivot joints (e.g., neck vertebrae) are examples of other types of joints.
