The correct answer is Spanish. This is because the Spanish were the first Europeans to settle in the Caribbean, followed by the French, English, and Dutch. The Spanish established colonies in the Caribbean in the late 15th and early 16th centuries, primarily in present-day Cuba, Puerto Rico, and the Dominican Republic. They were attracted to the region for its resources and strategic location for trade routes. The French, English, and Dutch later established their own colonies in the Caribbean, primarily for economic purposes such as sugar production.
