Detailed explanation-1: -The hip joint (see the image below) is a ball-and-socket synovial joint: the ball is the femoral head, and the socket is the acetabulum. The hip joint is the articulation of the pelvis with the femur, which connects the axial skeleton with the lower extremity.

Detailed explanation-2: -The round part of your femur fits into a cup-like socket in your pelvis called the acetabulum. This type of joint offers a wide range of motion and provides support for your legs to hold your body.

Detailed explanation-3: -The pelvis joints include the pubic symphysis and the lumbosacral, sacroiliac, and sacrococcygeal joints. The bony pelvis also articulates with the lower limb via the acetabulofemoral, or hip, joint on its lateral aspect.

Detailed explanation-4: -The SI joint is a diarthrodial synovial joint. It is surrounded by a fibrous capsule containing a joint space filled with synovial fluid between the articular surfaces.

Detailed explanation-5: -So, the correct answer is ‘ball and socket joint’
