The correct answer is D. The posterolateral surface
Explanation:
The ureters are bilateral structures that connect the kidneys to the urinary bladder; this is essential because urine needs to go from the kidneys to the bladder, where urine is temporarily stored before it is eliminated from the body. In terms of location, the ureters begin in the kidneys and then descend through the pelvis, finally, they enter the bladder at the sides and back of it; this implies the ureters enter in the posterolateral surface because the word posterolateral means on the sides and towards the back, which is exactly the location of the ureters in the bladder.
