The correct answer is C) offered its services as guides to settlers.

In those years, the Indian tribes that inhabited the Western territories of America saw in settlers the opportunity to offer their services as guides because they knew very well the geography of those territories. This helped in the increase of settlers in the region because in the early 1800s only 10% of colonizers lived West the Appalachians Mountains. But by 1825, 30% of people lived between the Appalachians and the Mississippi River. American Indians guiding serve people to guide them through these new territories.
