Correct Answer: B
Explanation:
(b) A uriniferous tubule/nephron is a long tubule differentiated into four regions – Bowman’s capsule, proximal convoluted tubule, loop of Henle and distal convoluted tubule. Collecting ducts are the larger tubes, each receiving the collecting tubules of several nephrons. Collecting duct does not form a part of the uriniferous tubule.
