<span>religious divisions between Hindus and Muslims on the Indian sub-continent</span>
In order to maximize profits ,many businessmen in the 19th century resorted to unethical business practices and thus earned the name robber barons.
They did not physically rob people but they stole control over natural resources, paid unfairly low wages and pushed out their competition using questionable business practices .
While their practices weren't viewed as ethical, most of the 19th century robber barons didn't commit any illegal acts, though through their actions, new laws were enacted to prevent others from following their actions.
The answer would be C. the movement of plants, animals, people, and diseases between the old world and the new world.
Hope this helped!
