B) The woman is instructed to bear down, the width of the blades is horizontally turned, and the speculum is inserted downward at a 45-degree angle toward the small of the woman's back.
C) The blades of the speculum are inserted on a horizontal plane, turning them to a 30-degree angle while continuing to insert them. The woman is asked to bear down after the speculum is inserted.
