Final answer
The central idea of the text is that after tension and a revolution with the Mexican government, Texas won its independence and eventually became a U.S. state.option c is correct answer.
Step-by-step explanation:
The central idea of the text concerning the history of Texas is that after tension and revolution with the Mexican government, Texas won its independence and eventually became a U.S. state. This option most accurately reflects the events surrounding the Texas Revolution, the involvement and eventual withdrawal of Tejanos in the struggle, the influx of American settlers, the declaration of the Lone Star Republic, and the annexation of Texas as a part of U.S. westward expansion.
The Battle of the Alamo played a significant role in Texas's fight for independence by rallying American support, but the statement's scope is too narrow to represent the overall central idea.
The complexity of these events, culminating in Texas's annexation and the resulting conflicts, displays a broader narrative of territorial struggle, the politics of slavery, and the ideology of Manifest Destiny during American expansion.
