Answer:
A. Texas
Explanation:
"The Chisholm Trail was a trail used in the post-Civil War era to drive cattle overland from ranches in Texas to Kansas railheads. The trail was established by Black Beaver, a Lenape (Delaware) guide and rancher, and his friend Jesse Chisholm, a merchant."
"Today, some historians consider the Chisholm Trail to have started at the Rio Grande in Texas or at San Antonio, Texas. From 1867 to 1871, the trail ended in Abilene, Kansas. Later, Newton, Kansas, and Wichita, Kansas, each served as the end of the trail."
