Answer:
I'd say the correct answer is B) new religions such as Christianity and Islam were introduced into Africa
Step-by-step explanation:
From the map shown and from the dates given for the analysis, I can deduce that answer A) is incorrect because gold was well known in Central Africa (the kingdom of Mansa Musa proves it). The answer C) could be but the commercial relationship that started to be established between the European and African kingdoms was not enough to understand that the European languages were spread over the wide Central African territory.
Finally, answer D), although probable considering the religious precepts of Islam, is incomplete since we cannot judge the rights of women in the 14th century with the ideology of the 21st century and on the other hand, I do not have a comparison to judge what the rights of women were before the influence of other cultures.
