Answer:
A: Increased African trade with the new world.
Step-by-step explanation:
Timbuktu is a city in Mali and it encouraged Trans-Saharan trade. The Trans-Saharan trade routes promoted the growth of powerful trading cities during this period because valuable items like slaves, gold, and salt were traded. This increased the net worth of the cities and allowed for economic growth.
It also increased African trade with the new world due to its demand for more goods for trading in the Sub-Saharan region.
