Ghana was under British colonial rule, and its movement towards independence was halted during WWII, resuming in 1945. After this point, Kwame Nkrumah spearheaded the independence movement, establishing the first political party in Ghana and being democratically elected as the inaugural president of the independent nation.
On the other hand, Kenya was also a British colony, but its path to independence was marked by countless battles and devastating losses due to the Mau Mau uprising against British authority. Subsequently, Jomo Kenyatta was appointed the first president in 1963, amid ongoing internal strife leading to further casualties and devastation.
Therefore, the correct associations for Ghana are: led by Kwame Nkrumah and peaceful transfer of power.
In contrast, the accurate links for Kenya are: led by Jomo Kenyatta and the tumultuous Mau Mau uprising resulted in independence.
The legitimate choices for both Ghana and Kenya are: achieved independence post-1945, and previously a British colony.
