Answer: a. but Carson disobeyed him.
Explanation:
Christopher Kit Carson was commanded by Major General James H. Carleton to overcome the Navajo people by carrying out a scorched-earth campaign through their homelands, killing all Navajo men.
Since many of his Army volunteers quit, Carson decided to force the Navajo to surrender for a lack of supplies. He cut their food supply, burned their villages, massacred their livestock, and disabled water sources, leading the Navajo people to starvation and surrender.
