Answers

Answer:

The result of the Berlin Conference excluded the option B: stopping the slave trade. The Berlin Conference of 1884-1885 was a meeting of European colonial powers to carve up and establish boundaries for territories in Africa. The purpose of this conference was to create a system of international cooperation for the colonization and trade of Africa among the European powers.

The conference mainly focused on the partitioning of Africa without regard for the indigenous ethnic and cultural boundaries and economic activities. The European powers aimed to ensure effective colonial occupation and control over the African continent, which resulted in the arbitrary division of territories without any consideration for the social, economic, or religious aspects of African life.

In conclusion, the Berlin Conference did not prioritize stopping slave trade as one of its goals.
