C) distal convoluted tubule (DCT)
D) papillary duct
E) glomerulus

The distal convoluted tubule (DCT) lacks microvilli and is under aldosterone control for the reabsorption of sodium. The nephron loop also plays a role in reabsorbing sodium, but it has microvilli and is not under aldosterone control. The proximal convoluted tubule (PCT) has extensive microvilli for reabsorption of various substances, but is not under aldosterone control for sodium reabsorption. The papillary duct is part of the collecting duct system and is not directly involved in sodium reabsorption. The glomerulus is not a tubular structure and does not participate in reabsorption or sodium regulation.
