What was the first step in Ghana's independence? Kwame Nkrumah became the prime minister. A military coup seized power in the colony. Africans gained a majority in the parliament. Opposition political parties were banned.

The correct answer is Africans gained a majority in the parliament.

Up until then, it was like in every other colony in Africa, the Europeans controlled the parliament and legislature and since now the Europeans were a minority in the parliament they couldn't affect the legislature regarding Ghana's independence.
