The correct answer is O Mansa Kankan Musa. Mansa Musa, also known as Kankan Musa, was the tenth Mansa (emperor) of the Mali Empire. He is famous for his extravagant pilgrimage to Mecca, known as the hajj, in 1324-1325, during which he brought immense wealth to the cities he passed through and spread Mali's fame across the Islamic world.
