Which of the following is not listed among the four main diamond-producing regions today?

Explanation:
Diamond production today comes from a few major regions where economically viable diamond-bearing rocks are mined. Eurasia (Russia), North America (Canada), and Australia are well-established sources with active mining and long-running deposits. Antarctica, on the other hand, has no commercial diamond mines. The continent lacks known, economically viable kimberlite deposits and is protected by environmental treaties that restrict mining, plus its extreme conditions and infrastructure challenges make large-scale diamond production impractical. So Antarctica is not listed among the four main diamond-producing regions today, while the others are.
