Final answer:
The cold core rings formed by the Gulf Stream would most likely carry pollutants to the Atlantic Ocean and the Caribbean Sea, as these are the direct areas of influence of the Gulf Stream.
Step-by-step explanation:
Cold core rings formed by the meandering of the Gulf Stream could carry pollutants to the Atlantic Ocean and the Caribbean Sea. As the Gulf Stream originates in the Gulf of Mexico and flows along the east coast of the United States into the Atlantic Ocean, these are the areas most likely to be affected by any pollutants carried by the current. The other options listed (the Arctic Ocean and the Mediterranean Sea, the Pacific Ocean and the Indian Ocean, the Red Sea and the Black Sea) are not directly influenced by the Gulf Stream's current patterns.
