Extension of railroads + Invention of barbed wire + Overgrazing of land = Which of the following does the list above best describe? O A Decline of the railroads in Texas OB A decrease in demand for beef OC The expansion of the open range D The end of the great Texas cattle drives

Option D, The end of the great Texas cattle drives, is the right answer.

Explanation:

The Spanish settlers were the first to bring the longhorn cattle in North America. During the course of time, Texas became home to millions of longhorn cattle. The cattle ranchers of the area wanted to sell them in the markets of East and North for the reason the demand was high and the supply was low. Such cattle drives came to an end in the decade of 1880s for various reasons. The invention of barbed wire, the expansion of railroads and too many cattle grazed on the crowded ranges and thus there was not enough grass to feed them all, were some of the significant reasons.
