Final answer:
The Convention of 1836 met at Washington-on-the-Brazos, where Texas' independence from Mexico was declared and a constitution was drafted. The critical defeat of General Santa Anna's forces by the Texans took place at the battle of San Jacinto. Also, the Republic of Fredonia was an earlier, short-lived attempt at a republic preceding the Lone Star Republic. The correct option is B.
Step-by-step explanation:
The Convention of 1836 met in Washington-on-the-Brazos to discuss the temporary government of Texas during the Texas Revolution. This assembly declared Texas independence from Mexico and drafted a constitution for the new republic, which called for an American-style judicial system and the establishment of elected officials such as a president and legislature. It also determined slavery would not be prohibited in Texas, a factor that appealed to many wealthy Tejanos who supported independence, hoping for liberal reforms and economic benefits.
Additionally, Texans defeated the army of General Antonio Lopez de Santa Anna at the battle of San Jacinto, not at the Alamo, which is often remembered for its fierce defense and tragic fall before the victory at San Jacinto.
The Long Expedition attempted to establish a republic in Texas known as the Republic of Fredonia, which was short-lived. However, the independent nation that formed after the revolution came to be known as the Lone Star Republic until its eventual annexation by the United States.
