Indian removal made the Midwest safe

Out of the given choices, "Indian removal made the Midwest safe" was not a reason for westward expansion during the first part of the nineteenth century.

Answer: Option C

Explanation:

The expansion was laid based on the following reasons,

Population growth and availability of productive lands was sought towards west in comparison to the west. The decreased transportation costs was sought based on the technological advancement leading to feasible infrastructure of transport. The raised wages and productivity made it very easier for westward expansion.

On a single note, it can be said that the cost of land was sought of less value than the innovative technology being advanced during the westward expansion being the reason of its causation. Therefore, the westward expansion has been quite well studied and of all the option given, but the option C does not stand in concern.
