Final answer:
Mansa Musa impacted Europe through economic repercussions caused by the gold he distributed during his pilgrimage to Mecca in 1324, which led to inflation and affected European economies.
Step-by-step explanation:
Mansa Musa's impact on Europe can primarily be seen through his extravagant pilgrimage to Mecca in 1324, which had significant economic repercussions in the regions he passed through, including Europe. His journey, as recorded by various sources, notably the Egyptian scribe al-Omari, expressed the vast wealth of the Mali Empire. Mansa Musa distributed so much gold during his stay in Cairo that it caused a rampant inflation that lasted for a dozen years.
This economic disturbance affected not only Egypt but also the European economy to some extent due to the interconnected nature of trade at the time. Moreover, the sheer display of riches sparked European interests, which eventually contributed to the motivation for the exploration and colonization of new lands, including the Americas, in search of similar wealth. Therefore, the most accurate answer is B) Mansa Musa's pilgrimage to Mecca had economic repercussions in Europe.
