Answer:
The correct answer is A.
Step-by-step explanation:
Mexican Texas was a territory of Mexico between 1821 and 1836. After Mexico became an independent country in 1821, the population of Texas was only of 3,500 inhabitants, so the Mexican government sought to increase the population of its northern territories.
In 1822, the American entrepreneur Stephen Austin established the first white American settlement in Texas along the Brazos River. The Mexican government encouraged more settlers to move in to help develop the Texan economy. Thousands of Americans took on the offer and moved, most of them settling between the Colorado and Brazos River, and by 1834 there were over 30,000 Americans living in Texas, and only about 8,000 Mexicans. It was at the town of Washington-on-the-Brazos where Texan colonists declared their independence of Mexico in 1836.
