The correct answer is D. Both faced periods of religious conflict and violence.
Explanation
After achieving its independence, Algeria was governed until 1992 by the National Liberation Front (FLN), the year in which the war began after the first round of the 1991 elections, in which the most popular political party among the Muslims, the Islamic Salvation Front (FIS), remained as the favorite to win the elections until the Army suspended the elections and outlawed the FIS. So two armed groups were born; the Islamic Salvation Army, the armed wing of the FIS, and the radically Muslim Islamic Group, whose origins are not so clear, and which have carried out a policy of indiscriminate attack against the civilian population. This conflict has claimed the lives of around 100,000 people.
On the other hand. In Nigeria, there was a religious, cultural, and political war originating the inherited borders created by the colonial powers grouped collectives without a tradition of common authority or shared forms of conflict resolution. Therefore, the vast territory that the British included and called Nigeria brought together three nations and many smaller ones with different linguistic criteria, and ethnic groups. What produced a Civil War known as the Biafra War, in which southern groups sought a division and form an independent state of Nigeria. According to the above, it can be affirmed that Nigeria and Algeria faced periods of religious conflict and violence. So, the correct answer is D. Both faced periods of religious conflicts and violence.
