Lexi started with  CD¯¯¯¯¯¯¯¯  on her paper. She folded her paper so that point  C  was on top of point  D . Then, she unfolded her paper and labeled the intersection of the fold and the line segment with point E .​ She used a straight edge to draw  QR←→  at an arbitrary angle through point  E . Finally, she drew  CR←→  through points  C  and  R  and  DR←→   through points  D  and  R . Which line segment or line is the segment bisector in this scenario? 

Options

CR
QR
DR
CD
