Vedclass · Answer

(D) The mandible is the only movable bone in the skull,which allows for chewing and speech. When walking,the swinging motion of the arms helps in maintaining balance and counteracting the rotation of the torso. Cartilaginous joints,such as those between adjacent vertebrae,allow for limited movement due to the presence of cartilage between the bones. Since all three statements are scientifically accurate,the correct option is $D$.
