A. The European powers did not invite any Africans.
Explanation:
Berlin Conference 1884-85 also known as the Congolese Conference and West African Conference regulated European colonization and trade in Africa,
in other words legalized the wars, exterminations and looting of an entire continent. This period was even officially known as the New Imperialism (the old one referred to the colonization of the American continent from the 15th to the beginning of the 19th century).
The conference was organized by Otto van Bismarck, the first German chancellor, and Germany, as then a new imperial force, led European forces (mostly colonialists from the period of the "first imperial wave") into unprecedented overseas looting, while the Berlin Conference formalized and stepped up its campaigns with a General Act to the African continent (the so-called Scramble of Africa).
