The correct answer is B) European nations wanting the biggest and richest colonies in Africa.
The Scramble for Africa refers to "European nations wanting the biggest and richest colonies in Africa."
After the Berlin Conference of 1844-1845, European superpowers agreed on regulating the split of the African Continent. These European superpowers such as France, Germany, Great Britain, Spain, and Portugal split the African territory, displaced people, and created new borders in order to colonize the territories.
What Europeans really wanted was to exploit the many raw materials and natural resources that were abundant in Africa, in order to make big profits.
