Which of these was most responsible for putting an end to the type of discrimination seen here?

I'm sorry but you have not stated what type of discrimination you are talking about.

Please edit your question to include the type of discrimination and i will do my best to help you!

the mother countries succeed in doing that by using the colony's natural resources, facilities in a colony, they do not take good care of these facilities, causing them to fail. this has had negative and positive effects on the people of africa, they then governed through direct or indirect rule depending on the country.

hope thsi

i believe the answer would be 1.
