c. europeans had to find new trade routes to the east because the ottoman empire controlled and taxed existing routes.
d. europeans had to turn over their economic authority to venice, the only european city that the ottoman empire would trade with.

The correct answer is the following: option C. The Ottoman Empire affected European trade, as Europeans had to find new trade routes to the East because the Ottoman Empire controlled and taxed existing routes.

The Ottoman Empire was also known as the Turkish Empire which, from the 14th century and early 20th century, controlled much of the Southeast Europe, Western Asia, and Northern Africa. By holding so much power, the Turkish were able to intercept most of all the trade routes that Europeans used to use. This affected European trade, as Europeans now had to find new routes, in order to avoid the Ottoman Empire.
