Electrolyte imbalance can affect the normal function of the brain. Sodium is an important electrolyte maintains homeostasis in the body. Its primary function is to regulate water retention. Low sodium usually decreases serum osmolality. This combination of deficiencies is called Hypotonic hyponatremia.
A sudden drop in sodium and plasma osmolality can cause seizures. Brain function is affected because the water in the body, because start to flow from the extracellular spaces into the intercellular spaces. This causes the brain cells to swell and thus affecting its normal function. 
Therapy for this type is IV therapy, particularly hypertonic saline to replace the sodium in the body and normalize plasma osmolality and diuretics are given to aid in water excretion. Therapy should be done slowly and should be closely monitored. More swelling can developed when it is done too quickly. 
        
             
        
        
        
I believe the answer is C.
