Explanation:

During westward expansion in the U.S., growing eastern cities created a rising demand for agricultural goods. The West had vast, fertile land ideal for farming, so many people moved west to profit from this demand by growing and selling agricultural products. The other options are incorrect: the West was often more dangerous (conflicts with Indigenous groups, harsh conditions) and had smaller, more spread-out communities compared to the established East.

The demand for agricultural products was increasing due to growth of cities
