The correct answer is B. Plants and animals.
Explanation
Christopher Columbus was the Italian navigator who discovered the New World. In 1492 he requested the help of the Catholic kings of the Crown of Castile to give him three ships and resources for his first voyage. On this trip, he attempted to establish an alternative route to travel to the East Indies by encircling the entire land. Once he got the patronage of the Catholic kings he had to report every one of his discoveries to them. Once he reached the Caribbean islands, he believed that he had reached the East Indies and there he only found natural resources such as exotic plants and animals other than those of the Iberian Peninsula. However, to prevent the kings from ceasing to give him financial patronage, he decided to inform them that he had found wealth and precious metals. According to the above, the correct answer is B. Plants and animals.
