Tenskwatawa and his brother Tecumseh urge Native Americans to fight against Americans because they were under the belief that Americans are not good. Both of them even denounced the American way of living and pursued traditional way of life — lessons they always taught to their followers.
        
                    
             
        
        
        
It all depends on the definition of the term Modern Era. The word modern comes from Latin word modo, which means right now or just now. It was used for the first time during the Renaissance in Italy to bring attention to the great rediscoveries of sciences, the arts, history and politics of Classical antiquity and the subsequent discoveries and progresses accomplished like the Age of Discovery.
If such definition is used as the basis for this question then the answer is definitely C.The establishment of global empires.
Indeed, since during the previous periods, Empires were limited to their immediate geographic areas. There had been some attempts to explore areas that were located much farther like the Vikings and their travels to Greenland and North America. 
However, it was the Europeans: and to some lesser extent the Chinese, that actually discovered (in the literal sense of removing the cover) the Americas for the entirety of the world. The discovery paved the way for the emergence of Global Empires that were completely unprecedented in the history of humanity since they spanned several continents. For instance, the Global Spanish Empire Under Philip II of Spain in the 16th Century that spanned the continents of Europe, the Americas, Africa and Asia.
