The correct answer is C) hurt them when they gained their independence.
The majority of African nations were NOT given a say in government, which hurt them when they gained their independence.
Let's have in mind that after so many years of European control and dominion in the so-called "Scramble for Africa" from the end of the 1800s to the first decade of the 1900s, European powers exerted total control over African territories. African people had no voice or representation. So what happened after many African nations got their independence from these European powers was that they were not prepared to rule their countries and many rebellions started.
