Final answer:
The correct answer is option a) Sam Houston.
Step-by-step explanation:
The leader who commanded the forces that defeated General Santa Anna at the Battle of San Jacinto during the Texas Revolution was Sam Houston. On April 21, 1836, the Texas forces under Sam Houston took Santa Anna by surprise. The Texans were seeking revenge for earlier defeats, such as the Battle of the Alamo, where notable figures like Davy Crockett and Jim Bowie lost their lives.
Houston's army was vastly outnumbered, but they executed a sneak attack on Santa Anna's troops during their afternoon rest. The swift and decisive victory resulted in Santa Anna's capture, ultimately leading to the signing of the Treaties of Velasco, which ended hostilities and laid the groundwork for the recognition of the independence of the Lone Star Republic.
