The correct answer is C. After gaining independence from Mexico in 1836, Texas created its on government and remained an independent state until it joined the U.S. through annexation in 1846.

The Republic of Texas was an independent state in North America, which existed between March 2, 1836 and December 29, 1845, when the annexation of Texas to the United States of America occurred.

The decision of the Texans to annex to the United States caused a protest by Mexico because in the Treaty of Velasco, signed in 1836, it was enunciated that if Texas separated from Mexico, it could not be part of the United States.

When this happened, Mexico declared war on Texas, therefore, the United States, and the Mexican-American War started.
