The correct answer is: "the Pacific Ocean"
Spain is located in the Iberian Peninsula which, in turn, is located in the Southwestern edge of the European continent and separated from Africa by the Mediterranean sea. In fact, Africa is only a few miles away from the most Southern Spanish region. Spanish Northern coasts are located in the Cantabrian sea, while the Western Spanish regions (Galicia and the provinces of Cadiz and Hueva in Western Andalusia) are in the Atlantic Ocean.
