Answer:
The correct answer is A. Kwame Nkrumah, the first president of Ghana, was overthrown by his own military, because of his very friendly policy towards communist nations.
Step-by-step explanation:
Kwame Nkrumah was the first President of Ghana from 1960 to 1966, the year he was deposed by a liberal and anti-communist military coup, financed by American and British capital.
Nkrumah was a socialist, and sought to advance this ideology in the newly independent African nations. This posed a threat, since it could promote the emergence of communist regimes in the area, destabilizing the entire continent. In addition, he promoted a rapprochement towards the Soviet Union and China, as well as the nationalization of the economy of his country. All of this worried the Ghanaian military sector, which decided to end that threat through a military coup in 1966.
