correct answer B:
Hyponatremia refers to a low ECF sodium concentration. It tells you nothing about the ECF volume, which is dependent on sodium content. Since sodium is the main ECF osmole, the ECF osmolality is decreased (hypoosmolality) with hyponatremia. This will cause water movement into cells and increase intracellular fluid volume
