The correct answer will be option-B.

Explanation:

The European- Christopher Columbus discovered the new land in 1492 which was named later America. The Europeans used human labor to conquer the new land by carrying disease, war, and slavery to the new land.

They carried diseases like influenza, smallpox and other viruses to which the native population of America was not immune. This lack of immunity to the old world pathogens leads to the death of about half of the population that is 50,000 to 300,000 people.

Thus, Option-B is the correct answer.
