Concept:Colonialism produced both benefits and harmful effects for West Africa.
Explanation:Colonial rule created certain social and economic developments, such as roads, railways, and ports.
However, these same infrastructures were not built purely for the welfare of Africans.
They were constructed using forced labour from West Africans.
At the same time, they were deliberately designed to ease the exploitation of natural resources for colonial benefit.
This combination of visible development and underlying exploitation makes colonialism a double-edged sword.
Answer:A. The infrastructure built from West African forced labour was also designed to exploit their natural resources.
