Final answer:
Ghana gained independence from colonial rule on March 6, 1957, becoming the first country in Sub-Saharan Africa to do so, led by Kwame Nkrumah and his party in the context of post-World War II decolonization. Option b) is correct.
Step-by-step explanation:
Ghana gained independence from colonial rule on March 6, 1957. Leading up to this moment, there was significant resistance to British colonial powers. After World War II, many African colonies pursued independence, culminating in Ghana becoming the first country in Sub-Saharan Africa to achieve this status. The path to independence was led by figures like Kwame Nkrumah, who founded the Convention People's Party and was instrumental in the movement for self-rule. After a period of political activism, protests, and incarceration of leaders, the British government eventually relented, leading to the founding of an independent Ghanaian state.
The struggle for independence in African colonies such as Ghana showcases the weakening grasp of European colonial powers after the devastation of World War II and the rise of nationalism in the colonies. The process of decolonization was widespread across the continent, but Ghana's journey became a significant symbol of freedom and inspired other colonies to continue their fight for sovereignty.
