The answer is: C
Loss of gastric juice results in hypokalemic, metabolic alkalosis. Excessive loss of fluid from the gastrointestinal tract can lead to dehydration and, depending upon the origin of the fluid loss, electrolyte and acid-base disturbances. The hydrogen ion and potassium ion concentration of gastric juice exceeds that of the plasma. As a result, excess fluid loss leads to metabolic alkalosis accompanied by hypokalemia. Because the pancreas, liver, ileum, and colon secrete bicarbonate, excessive loss leads to metabolic acidosis. In addition, the colon secretes potassium. Thus, the acidosis is accompanied by hypokalemia.

also one point,insulin controls K+ level in ECC,as it pumps k+ inside the cell(ECF-->ICF),so b/c of this effect its used in life threathin' HYPERKALEMIA(acc to kaplan,hyperkalemia is nothing but more K+ from ICF into ECF and v&v.
