c/These areas have the climatic conditions needed to grow cotton.

Explanation:

The climatic conditions in southwestern and central Oklahoma favor the growth of crops that are sturdy enough to sustain the variations in the atmospheric conditions throughout the year.

After the Civil War ended, the availability of labor became a serious problem, owing to which, the farmers had to make their families and other coworkers work in their farms during the harvesting seasons.

It was not until the 1920s that a dedicated market was established for cotton. Though cotton had great demand, it did not have a dedicated market for many decades.
