What is the answer?
The correct answer to this question is A. It was founded by Sunni Ali the Great. The answer is Sunni Ali because he was the founder of the Songhai Empire and the first king of this empire as well.
Why is this answer correct?
If you want further proof, you could search up "Who founded the Songhai Empire?" and Sunni Ali will be the first one to pop up.
Since we know that Sunni Ali was the person who founded the Songhai Empire, then we can automatically eliminate answer choice B, because it was definitely not founded by Sundiata Keita. Sundiata Keita was the founder of the Mali Empire. He was also a prince of the Mali Empire.
Answer choice C is incorrect because the Songhai Empire was actually the largest out of the three major West African Empires, not the smallest.
Answer choice D is incorrect because the Songhai Empire fell because a Moroccan army attacked the capital of the empire during its weakened state; the Songhai Empire did not fall because of climate change which is why D is not the best answer.
