Hyaline Cartilage joints in the maxilla.
None.
Fibrous Cartilage joints in the Skull.
Hyaline Cartilage joints in the ribs.
The Correct Answer is D
A cartilaginous joint is a joint where the bones are united by cartilage.
A hyaline cartilage joint is a type of cartilaginous joint where the bones are joined by hyaline cartilage.
An example of a hyaline cartilage joint is the first sternocostal joint that unites the first rib to the sternum.
Choice A is incorrect because hyaline cartilage joints are not present in the maxilla.
The maxilla is a single bone that forms the upper jaw and palate. Choice B is incorrect because none is not a valid answer.
Choice C is incorrect because fibrous cartilage joints are not present in the skull. The skull bones are joined by fibrous joints called sutures.

Correct Answer is B
Explanation
A ligament is a type of fibrous connective tissue that connects bone to bone. It usually serves to hold structures together and keep them stable.
For example, the anterior cruciate ligament (ACL) connects the femur and the tibia in the knee joint.
Choice A is incorrect because none of these is not a valid answer.
Choice C is incorrect because tendons are fibrous connective tissues that connect muscle to bone.
For example, the Achilles tendon connects the gastrocnemius muscle to the calcaneus bone in the ankle.
Choice D is incorrect because syndesmosis is a type of fibrous joint that connects two bones by a ligament or an interosseous membrane.
For example, the distal tibiofibular joint is a syndesmosis joint.
Correct Answer is ["Acetabulum"]
Explanation
acetabulum is the concave cavity located on the lateral surface of the hip bone.
It is formed by the fusion of the ilium, ischium, and pubis bones.
The acetabulum articulates with the head of the femur to form the hip joint, which is a ball-and-socket joint that allows for a wide range of movement.
The acetabulum is lined with articular cartilage, which provides a smooth surface for the head of the femur to move against.
The acetabulum is also surrounded by a fibrocartilaginous ring called the acetabular labrum, which deepens the socket and helps to stabilize the hip joint.
Injuries to the acetabulum can result in hip dislocations or fractures, which can be very painful and require medical intervention.
