The correct answer is option 2, the Seas of China and Japan. Typhoons, also known as tropical cyclones, are common in this region. Option 1, the Arctic Ocean, is not a region where typhoons occur frequently; instead, it is more likely to experience ice storms and blizzards. Option 3, the Mexican Gulf, is also not a location known for typhoons; instead, it is prone to hurricanes. Option 4, the Indian Ocean, does experience cyclones, but they are called tropical cyclones rather than typhoons. Therefore, the correct answer is option 2, as the Seas of China and Japan are well-known for the occurrence of typhoons.
