(2) Islam became a major religion in the Balkans.
(3) Trade was disrupted throughout the Indian

Answer 1

"(2) Islam became a major religion in the Balkans" would be the option that best describes an effect of the westward expansion of the Ottoman Empire under
Suleiman the Magnificent since Islam was the prominent religion of the empire. 

Answer 2

(2) Islam became a major religion in the Balkans.

As the Ottoman Empire expanded, Islam expanded with it. The Ottomans were able to expand into Eastern Europe and therefore the religion of the empire also expanded. Though most of the Ottoman leaders allowed for religious toleration, there were benefits for people to convert to Islam. There were less taxes and more opportunity for education and military service.
