it is vital to the kiowa tribe that they maintain their lifestyle.
the kiowa tribe is going to stubbornly remain on their land.

Explanation:

The excerpt contrasts the Kiowa's freedom and happiness while roaming the prairies with the harm of settling down. This directly ties to the importance of keeping their traditional nomadic lifestyle. The other options do not align: there is no mention of peace with white settlers, soldier threats, or stubbornly staying on land—only the vital link between their lifestyle and well-being.

Answer:

It is vital to the Kiowa tribe that they maintain their lifestyle.
