The correct answer is D, as Ghana is thriving more than other nations in Africa because after Jerry Rawlings seized power in 1981, he introduced economic reforms in the country.
Rawlings attempted a failed coup d'état in 1979, which resulted in his arrest and sentencing to death. However, before the execution, he was released by a group of related military officers that, led by Major Boakye Djan, toppled the military government of General Fred Akuffo in the coup of June 4, 1979. That same year elections were held and the third republic was installed. However, Rawlings returned to lead a coup in 1981 and was installed in the government with the PNDC (Provisional National Defense Council)
The initial revolutionary measures, such as the control of prices and the nationalization of economic activities, proved ineffective in reducing inflation and overwhelming poverty. Thus, since 1984 Rawlings opted for a radical policy of structural adjustment and reforms in favor of the free market, which included privatizations in the key productive sectors of cocoa, gold and wood.
Very concerned about the agricultural development of his country, Rawlings gave maximum importance to small farming centers to achieve self-sufficiency in some staple foods, as well as industrial cooperatives and women's organizations. The economic growth of Ghana in these years was, however, similar to high unemployment and inflation, and, since the mid-nineties, to the financial crisis caused by the fall of the international prices of gold and cocoa. All this revealed serious uncertainties about the sustainability of sustained development.
