D. markets in the East and Midwest

Explanation:

After the Civil War, the demand for cattle grew significantly. New markets had arisen, including the US army in the West, the Indians on reservations, miners and railroad builders. Moreover, the taste for beef had grown, and the railroads made transportation easier. These reasons led to the rise of cowboys, who led cattle drives through Indian territory to the growing markets in the East and Midwest.
