The answer is: A
During childbirth, sex hormones and the release of relaxin allow loosening of several joints including the sacroiliac joints and the pubic symphysis. This, however, does not change the position of the sacral promontory relative to the pubic symphysis. Loosening of the pubic symphysis does allow the pubic rami to separate slightly, increasing the lateral diameter of the pelvis. Posterior rotation of the coccyx increases the anteroposterior dimension of the pelvic outlet.

@ good_boy_1234...it is in step 1 Q bank...
