The term "girdles" refers to the bony structures that connect the upper and lower extremities to the axial skeleton. These include the pectoral girdle (clavicle and scapula) and the pelvic girdle (ilium, ischium, and pubis bones). Thus, choice B is the best answer. Joints, ball and socket, and rotator cuffs are not supporting elements of the appendicular skeleton, and sutures are only found in the skull, which is part of the axial skeleton.
