Three individuals,each weighing 55 kg and each having a plasma [Na⁺] of 145 mEq/L,receive infusions of different solutions.Individual A receives 1 L of isotonic NaCl (290 mOsm/kg H₂O); individual B receives 1 L of a mannitol solution (290 mOsm/kg H₂O); and individual C receives 1 L of a 5% dextrose in water (D₅W)solution (290 mOsm/kg H₂O).Assuming that there is no urine output,and after complete equilibration of the extracellular and intracellular fluid,which of these individuals will have a lower plasma [Na⁺]?

A)Individual A (NaCl infusion).
B)Individual B (mannitol infusion).
C)Individual C (D₅W infusion).
D)Individuals A,B,and C will have the same plasma [Na⁺].
