that happened due to the

The correct answer is letter B.

Explanation: The arrival of the Genoese navigator in America provides natives of the New Continent or contact with a plethora of microorganisms that were not known to them. The most striking example was a variable, which was nonexistent on the American continent and was brought with Europeans. The result was the extermination of the American population through disease rather than wars. Ignorance of the causes of diseases caused by indigenous people does not isolate patients, thus avoiding the contagion of other inhabitants of a village. Since they did not know that microorganisms were also transmitted by air, when a village was infected, a disease spread, leading some of the inhabitants to seek refuge in another village, spreading as diseases and as deaths.
