How did the Sapa Inca strengthen his rule?

A) by redistributing lands and herds among citizens

B) by promoting trade with neighboring peoples

C) by imposing one language and religion across the empire

D) by building schools to train people from all classes to serve in a civil bureaucracy

The correct answer is A) by redistributing lands and herds among citizens. He did it because then the people who owned the lands started supporting him and since the farmers were supporting him, there was nothing that the local smaller nobles could do so everyone had to accept him as the ruler of the Incas.
