The correct option is A 3 ions of Na+ are pumped out and 2K+ are taken in
Energy from ATP cause conformational change in the solute carrier complex. From the energy of one ATP, three Na+ ions are pumped outside and two K+ ions taken in. This process of expelling out Na+ ions and drawing in K+ ions against the concentration gradient or electrochemical gradient is called sodium-potassium exchange pump of the cell.
