Correct answer choice is:
A. His lavish pilgrimage to Mecca made the empire of Mali and its wealth widely known.
Step-by-step explanation:
Mansa Musa was the tenth Mansa, which transposes to "sultan", "conquistador", or "monarch", of the prosperous West African Mali Empire. He became ruler in 1307. He was the leading African leader to be broadly recognized in Europe and the Middle East. Mansa Musa was the famous nephew of Sundiata Keita, who was the patron of the realm. Throughout his rulership Mali may have been the greatest generator of gold in the world; it was at a time of extraordinary market for the goods. His extensive pilgrimage to the Muslim holy city of Mecca in 1324 introduced him to leaders in the Middle East and in Europe.
