• A. Sodium ions (Na⁺) into the cell, potassium ions (K⁺) out of the cell
• B. Sodium ions (Na⁺) out of the cell, potassium ions (K⁺) into the cell
• C. Both sodium ions (Na⁺) and potassium ions (K⁺) move into the cell
• D. Both sodium ions (Na⁺) and potassium ions (K⁺) move out of the cell

Answer: (B)
