Question

the economies of most african colonies were dependent on
industrial development.
one or two crops.
a strong middle class.
diverse farmlands.

Explanation:

Colonial powers structured African economies to serve their own needs, focusing on the production of a small number of cash crops (like cotton, coffee, or palm oil) for export to the colonizing nation. This created a monocrop or dual-crop dependent system, with little industrial development, limited middle class growth, and no emphasis on diverse, subsistence-focused farmlands.

Answer:

B. one or two crops.
