The correct answer is number 2) the central location spanning Europe, Africa, and Asia.

The factor that most contributed to the cultural diversity of the Ottoman Empire was the central location spanning Europe, Africa, and Asia.

The powerful Ottoman empire was also very rich in culture, tradition, and arts for the many territories it occupied. There was a mixture of former Islam, Arab, Persian, and Greek culture that made the Ottoman Empire relevant in culture. It also helped that the Ottoman Empire showed tolerance to the many religions practiced in its territories to not only maintain peace and stability but to allow cultural expression to flourish.
