The distal convoluted tubule (DCT) does reabsorb sodium, but not the majority of it !! Sodium handling by segment - Proximal convoluted tubule (PCT): ~65–70% - Thick ascending limb: ~25% - Distal convoluted tubule (DCT): ~5% - Collecting duct: ~2–3%

@Safwat Mohamed I thought “C” at first too but thinking about it won’t the 6 hours pre-op be too early for standard surgical prophylaxis ? As antibiotic levels may no longer be optimal at the time of incision!
