Which of the following regions does NOT belong to the Caribbean?

The Gulf of Mexico is the correct answer because it is a body of water bordered by mainland North America and is not considered part of the Caribbean region itself. The Caribbean comprises islands and coastal areas that are characterized by their unique cultural, historical, and geographical attributes that distinguish them from the Gulf of Mexico, which primarily surrounds the southeastern United States, Mexico, and parts of Cuba.

The Bahamas, the Lucayan Archipelago, and the Greater Antilles are all integral parts of the Caribbean. The Bahamas consists of numerous islands within the Atlantic, known for their tropical climate and tourism. The Lucayan Archipelago includes the islands of the Bahamas and is specifically recognized as part of the Caribbean island grouping. Additionally, the Greater Antilles encompasses a group of larger islands in the Caribbean, including Cuba, Jamaica, Hispaniola (Haiti and the Dominican Republic), and Puerto Rico, which are all culturally and geographically linked to the region.
