The correct answer is option d. "secondary active transport by an antiporter".
Explanation:
The cotransport of calcium and sodium at which one calcium ion moves out of the cell and three sodium ions move into the cell is known as secondary active transport by an antiporter. It is secondary because it uses a form of energy different from ATP, is an active transport because the calcium ion moves against its gradient, and its done by an antiporter which is an integral membrane protein that function as a cotransporter.
