The correct answer is B. Spanish monarchs tried to end the encomienda system because they believed that it was immoral and, thus, anti-Christian.
Explanation:
The denunciations against the mistreatment of the natives by some encomenderos, never by mandate of the Spanish Crown, and the advent of the so-called demographic catastrophe of the indigenous population, caused the encomienda to enter into crisis at the end of the 17th century, although in some places it survived until the 18th century. The encomienda was being replaced by an open slavery system composed of many thousands of people kidnapped and hunted in Africa, and forcibly taken to Spanish America in terrible conditions through the so-called "slave ships".
