A. Large numbers of Nativa Americans died due to exposure to European diseases.

Explanation:

Europeans who came to the Americas brought diseases that had devastated the old world for centuries, such as smallpox and measles. Europeans had resistance to these diseases thanks to centuries fighting them and innovating in medical techniques to fight them. Because the Native Americans had no resistance to these diseases, they were brutally affected, the death toll is much more due to these diseases than the dead due to conquest and forced labor. Additionally, the discovery of quinine allowed Europeans to have a treatment against malaria and thus be able to advance their conquest in the new world, affecting a greater number of Native Americans in its path.
