The answer to this question is A. Mali.

Mansa Musa was indeed the ruler of the African kingdom of Mali. To find the correct answer, one can use various methods. Let me explain one way to approach it:

1. Knowledge: If you already have prior knowledge or have studied the history of African kingdoms, you might remember that Mansa Musa was closely associated with Mali.

2. Logical reasoning: You can eliminate the answer choices by using logical reasoning. For example, you can eliminate Morocco because it is a neighboring kingdom and not the same as Mali. Similarly, you can eliminate Ghana and Egypt since they were separate kingdoms in different regions of Africa.

3. Research: If you are unsure or want to confirm your answer, you can conduct a quick internet search specifically for Mansa Musa. This will provide you with multiple reliable sources that will confirm that Mansa Musa was the ruler of the African kingdom of Mali.
