The correct answer is 720 pounds.

After 4 hours, the amount of algae in the pond will double to 180 pounds.
After 8 hours, the amount of algae in the pond will double again to 360 pounds.
After 12 hours, the amount of algae in the pond will double once more to 720 pounds.

Therefore, after 12 hours, there will be 720 pounds of algae in the pond.
