It is D, the ottoman empire. It' not A because the byzantine's were part of the ottoman empire. The Mongols were eastern asia so that wouldn't be it. And the roman empire had already fell by the time the Ottoman empire had rose. So you have your answer! Hope I helped. :)
The last great empire centered in Southwest Asia was the Ottoman Empire, founded in the late 13th century and lasting until 1922. It expanded significantly, reaching its height under Suleiman the Magnificent in the 16th century, controlling vast territories in Europe, Asia, and Africa. Its capital was Constantinople, and the empire is known for its military prowess and cultural contributions.
