Answer:
A) It facilitated cultural exchange between Asia and the Middle East.
Step-by-step explanation:
This answer makes the most sense because the Silk Road was the main reason why there was cultural exchange between these two regions.
Judaism and Islam did not spread from China to other regions, in fact Judaism originated in Israel while Islam originated in Saudi Arabia.
D makes absolutely no sense because there's an ocean between these continents, and the silk road was definitely not a water-way trade route.
