The question here stated that the patient was stabbed beneath the 12th rib grazing the inferior pole of the left kidney.
From this you have to know the anatomical associations with the left kidney. The left kidney is in contact with the spleen, stomach & splenic flexure.
Out of these 3 options you have the stomach and Splenic flexure anterior to the kidney but what makes the splenic flexure the best answer is the description of where the he was stabbed. Stomach will be higher up than the splenic flexure.
Apply the same concept to the left kidney!
Hope this helps

hit the kidney so retroperitoneal. leaves only the duodenum and splenic flexure. kidneys are more lateral structures so splenic flexure (at turn of descending colon)
