Final answer:
Option (a), The tribe that attacked Mission San Antonio de Valero (the Alamo) was the Comanche, but the more famous Battle of the Alamo was between Texan defenders and the Mexican army.
Step-by-step explanation:
The tribe that attacked Mission San Antonio de Valero, also known as the Alamo, was the Comanche. This event was part of the wider conflict surrounding the Texas Revolution, which was a pivotal moment in the history of Texas transitioning from a Mexican province to becoming a part of the United States. Notably, the battle famously associated with Mission San Antonio de Valero, the Battle of the Alamo, was primarily between Texan defenders and the Mexican army led by General Antonio Lopez de Santa Anna, and not a Native American tribe.
However, the Apache were also known to have conflicts with Spanish missions, including the Alamo, during the Spanish period in Texas, before the Texas Revolution.
