The correct option is B South Africa
South Africa accounts for about 33.5% of the global manganese production. The country has an annual manganese production of 6.2 million tons, which is the largest not only in Africa but in the whole world. Most of the manganese mining in South Africa is concentrated in the Kalahari Desert which is believed to contain over 70% of the global manganese reserves. Manganese mining is a principal employer in some regions of the country and earns the country millions of dollars in foreign exchange.
