<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 5-year-old boy is brought to the clinic for recurrent bedwetting. The child has an intellectual disability; thus, the mother is providing most of the history. She states that the child constantly drinks fluids and has a difficult time making it to the bathroom as often as he needs. Therefore, he sometimes wets himself during the day and at night. She has tried bedwetting alarms with no success. Review of systems is negative. His past medical history is unremarkable expect for moderate growth retardation. His temperature is 99.5F 37.5C, blood pressure is 8054 mmHg, pulse is 90min, respirations are 20min, and oxygen saturation is 99 on room air. Routine laboratory tests and a 24 hour urine test are shown below.Serum:Na: 138 mEqLCl-: 90 mEqLK: 2.5 mEqLHCO3-: 35 mEqL BUN: 9 mgdL Glucose: 98 mgdLCreatinine: 1.0 mgdLThyroid-stimulating hormone: 1.2 μUmLCa2: 9.1 mgdLAST: 13 ULALT: 10 ULpH: 7.49Urine:Epithelial cells: 5 cellsGlucose: NegativeWBC: 0hpfBacterial: NoneProtein: 60 mg24h Normal: 150 mg24hCalcium: 370 mg24h Normal: 100-300 mg24hOsmolality 1600 mOsmolkg H2O Normal: 50-1400 mOsmolkg H2OWhat is the most likely explanation for this patients findings?? A: Defect of NaCl reabsorption at the distal collecting tube, B: Defect of NaK2Cl- cotransporter at the thick ascending loop of Henle, C: Generalized reabsorptive defect in the proximal collecting tube, D: Hereditary deficiency of 11B-hydroxysteroid dehydrogenase, E: Increased sodium reabsorption at the collecting tubules,  <response>: Based on the information provided in the question stem, this is a case of a 5-year-old boy with recurrent bedwetting, intellectual disability, polydipsia, polyuria, and inability to control urination. The lab tests show low potassium, elevated urine osmolality and calcium. This suggests a defect in the renal concentration and dilution mechanism. The increased urine osmolality indicates the kidneys inability to dilute urine maximally. The elevated urine calcium indicates impaired reabsorption of calcium in the distal nephron. B: Defect of NaK2Cl- cotransporter at the thick ascending loop of Henle
