C. Access to farmland / good soil / land.
Step-by-step explanation:
In the 1800s, numerous people in the US moved westward because of the access to farmland, good soil, and land. This era is often termed as the age of US territorial expansion or the Manifest Destiny.

Many believe that in the 19th century, people were destined to expand across North America, hence the name.
