Final answer:
The rallying point for Texas colonists to fight their own revolution was The Laws of April 6, 1830, analogous to the American colonists' response to the British Stamp Act. Option 3 is correct.
Step-by-step explanation:
The rallying point for Texas colonists to fight their own revolution was The Laws of April 6, 1830. Much like the British Stamp Act served as a catalyst for the American colonists to unite against what they felt were oppressive policies imposed by the British government, the Laws of April 6, 1830 provided a similar impetus for Texans. These laws, imposed by the Mexican government, sought to stop the further immigration of Americans into Texas and to impose custom duties, causing resentment and helping to precipitate the Texas Revolution.
