<em>C.) The Columbian Exchange.</em>
Explanation:
The Columbian Exchange was the exchange of plants and animals between the Old and New World.
The Columbian Exchange was a huge exchange of animals, plants, ideas, technology, and even diseases. Many different countries grew and the spread of cultures was very evident. Most of the trade would happen between the Old World, which was Europe, and the New World, which was the Americas.
Many of the plants and animals we see today are products of the Columbian Exchange. The dandelion originally came from Europe, along with many of the animals we eat.
The Triangular Trade and the Middle Passage focused on slavery, but the Triangular Trade did bring commodities here and there.
