Why did the Inca engage in continuous expansion? (1 point)
O The Inca lacked resources for their pastoral lifestyle, so they conquered grazing lands owned by other groups.
O Land could not be inherited by new rulers, so they had to expand the empire to gain more wealth and power.
O The need for laborers after the failure of the mit'a made it necessary to conquer new lands.
O The Inca's conflicts with the Wari and Tikawanu civilizations forced them to grow the empire for more power.
