Answer:
B. Domesticated animals such as cattle, horses, pigs, and chickens were introduced to the Americas by European colonizers. Prior to this, very few animals had been domesticated in the Americas.
Explanation:
The Columbian Exchange was named after the very popular voyager and explorer, Christopher Columbus. Columbian Exchange is also referred to as the Columbian Interchange and typically involved the widespread movement of commodities, plants, technology, cultures, diseases, people and animals across West Africa, the Atlantic, America and the Old world (Europe, Asia, and Africa) as far back as in the 15th and 16th century.
The impact of the Columbian Exchange was largely based on the transfer of livestock, ideas, and diseases into America by the European colonizers. Some examples of the animals transferred from Europe to the Americas are goats, sheep, cattle, chickens, rats and pigs. The diseases transferred from Europe to the Americas, for which they had no immunity include typhoid, cholera measles, and smallpox.
Basically, the Columbian Exchange had a great impact on the people of America by significantly transforming their lives.
Hence, the scenario that best explains the Columbian Exchange is that, domesticated animals such as cattle, horses, pigs, and chickens were introduced to the Americas by European colonizers. Prior to this, very few animals had been domesticated in the Americas.
