The statement that best explains why Baghdad was an important city during medieval times is:

It was a capital city along major trade routes.

Explanation:

During the Abbasid caliphate in the 8th century, Baghdad was its capital and the cultural, commercial, and intellectual center of the Muslim world.   With its location on the Tigris River in the very heart of the ancient Mesopotamia, where the Tigris flows closest to the Euphrates, it was ideally placed for global trade.  Within the same period, Baghdad provided important crossroads for trade by land and sea, serving as a central hub for the region.
