Answer
A. Renal papilla Explanation: ZIFT- The distal convoluted tubules of a number of adjacent nephrons open into a common collecting duct or tubule. Collecting ducts (present in medullary pyramids) are long tubules, which traverse through the medulla in the pyramids and opens in the papilla of the medulla (in rabbit) or papilla of the individual medullary pyramid (in human). Several adjacent collecting ducts converge to open into a common short and thick duct of Bellini (present in papilla of medulla). All ducts of Bellini then open at the tip of the papillae into the pelvis.
