Which of the following countries are among the top six uranium producers?

• A. Kazakhstan, Canada, Namibia, Australia, Uzbekistan, Russia
• B. United States, Canada, Namibia, Australia, China, Russia
• C. Kazakhstan, Canada, Brazil, Australia, Uzbekistan, Russia
• D. Kazakhstan, Canada, Namibia, Germany, Uzbekistan, Japan

Answer: (A)

The key idea is knowing which countries produce the most uranium in mining. The largest producers are typically Kazakhstan, Canada, Australia, Namibia, Uzbekistan, and Russia, making up the top tier of global supply. That set of six appears in the option chosen, reflecting the common ranking of leading uranium producers in recent years. The other choices include countries with little or no current role as major uranium miners (like Germany, Japan, or the United States, depending on the year, and Brazil or China in some lists), so they don’t align with the top-six grouping. In short, this list matches the nations that most consistently appear in the top tier of uranium production.
