Concept:The referendum of 27 April 1960 asked Ghanaians whether Ghana should stop being a dominion with the British monarch as Head of State and become a republic with an elected president.
Explanation:Before the referendum, Queen Elizabeth II was Ghana's Head of State, represented by a Governor-General.
The people voted for the republican constitution, and on 1 July 1960 Ghana became a republic with Dr. Kwame Nkrumah as its first President.
The first political parties had been formed long before 1960, and Nkrumah had already been Prime Minister since 1952.
Queen Elizabeth II was never Prime Minister of Ghana.
Key point: The paper printed option C as 'Ghana became a democratic state'. Ghana was already a democracy before 1960; what changed after the referendum was that it became a republic, so the option is corrected.
Answer:Option C (Ghana became a republic)
