Which of the following is NOT one of the oceans of the world?

The Coral Sea is not classified as one of the major oceans of the world. Instead, it is a body of water located in the southwestern Pacific Ocean, bordered by Australia and parts of the Solomon Islands. The major oceans recognized globally are the Atlantic, Indian, Southern (or Antarctic), Arctic, and Pacific Oceans. The Atlantic and Pacific are two of the largest oceans, while the Indian Ocean serves as a critical maritime route between several continents. The presence of the Coral Sea might lead to confusion, but it is significantly smaller and categorized as part of the Pacific, rather than being a distinct oceanic entity. Understanding the distinctions between oceans and seas is fundamental in environmental studies, as it impacts marine life, climate patterns, and global trade routes.
