The statement that accurately explains how the boom-and-bust cycle affected a specific set of Texas industries is:
A surplus of open-range cattle during and after the Civil War resulted in a boom in both the cattle and cotton industries.
This statement reflects the historical context where a significant increase in cattle after the Civil War, due to the availability of open-range grazing, led to a boom in the cattle industry, which also positively affected related agricultural sectors like cotton due to increased land use and demand for agricultural products.
The other statements either do not accurately reflect the relationship between the industries or misrepresent the effects of economic booms and busts on those industries.
