Ans. A, B & C
The pelvic bones are stabilized by supporting ligaments. These ligaments include ligaments of the symphysis pubis, the anterior and posterior sacroiliac ligaments, the iliolumbar ligament that attach the transverse processes of L5 to the sacroiliac joint ligament, the sacrospinous ligaments, and the sacrotuberous ligaments.
The stability of pelvic ring also depends on the SI joints and the pubic symphyses, both of which are fibrous joints and only allow minimal movements Inguinal ligament and external oblique aponeurosis play no role in providing stability to pelvic ring.
