Answer:
C.
Step-by-step explanation:
The birth of cattle ranching in Oklahoma began with the settlement of Five tribes in the western portions of Indian territory. After Louisian Purchase, Native Americans were shifted to west of the Mississippi river. The settlement of Five native tribes (Cherokee, Chickasaw, Choctaw, Creek, and Seminole) in the 1830s made the cattle ranching profitable in the future state of Oklahoma.
The natives brought with them a large number of herds and cattles and the practice of open grazing. With extended grass lands, the herds of natives began to multiply and the Natives nation began to have huge number of cattles, which made cattle ranching profitable.
Therefore, option C is correct.
