Answer:
Now im not sure but i have a few guesses, A, or D
Step-by-step explanation:
A)
Africa geographic features such as (deserts, rain forests, and rivers) were difficult to navigate, because not only Europe had no jungle, but also no deserts, i would debate over rivers but a few of the rivers were huge in Africa, to tell you how huge it is, the Nile, Congo, and the are the top 3 longest rivers so far (why im saying so far is because they can make man made rivers, i doubt it tho)
B)
Europeans had a lot of interest in African people territory for sure, but what about the Americas? the Americas were found in the 1492, it is a possibility this answer is correct but maybe its not.
D)
Diseases, such as one of the strongest diseases, prevented Europeans from occupying territories, this is true too as diseases was in its prime time in the 1890's also it was discovered in Africa.
E.
Africa had no important natural resources, i could debate with this cause, south Africa had sure lot of diamonds, that's why the UK was in Africa the whole time, not only south Africa tho, there is also Mali that had a lot of gold made in the past, there are rich country's and you don't think the French, Spaniards, British, Portuguese, and the Germans are not going to colonize them!?
F)
Europeans argued over what country would invade first. again, i could flat out debate this as if you don't know, Europeans are out to settle, not to be civilized to any of their neighbors.
