According to Weige Meyer rule of duplication of ureter, the lower pole ureter in urinary bladder is: 
Select and explain. 
A. Lateral and cephalad to the upper pole ureter, B. Lateral and caudal to the upper pole ureter, C. Medial and cephalad to the upper pole ureter, D. Medial and caudal to the upper pole ureter
