The attachments of the quadratus lumborum are the twelfth rib and the transverse processes of L1-L4 to the posterior iliac crest. Option B is incorrect as it mentions the spinous processes instead of the transverse processes. Option C is incorrect as it refers to the medial lip of the bicipital groove of the humerus which is not related to the quadratus lumborum. Option D is incorrect as it mentions the anterior iliac crest instead of the posterior iliac crest.
