The most accurate answer would be b. was the result of increased competition for open range.

The correct answer is B. Was the result of increased competition for the open range.

Explanation:

The cattle boom refers to an important increase of cattle ranching that began in 1860 and cause hundred of ranchers to raise cattle mainly in the Great Plains of the U.S. These ranchers depended on open range that refers to rangelands, which are territories covered by grass or shrubs, where cattle could feed freely and where there was no restriction of ownership of land. As a result of multiple ranchers taking cattle to open range, most of the grasses and shrubs of the Great Plains were destroyed and thus, it became difficult for ranchers to find new territories to feed their cattle, this means the competition for open range increased and as a result of this, by 1880 the cattle boom had ended as ranchers were unable to find new territories and could not raise cattle massively anymore.
