The correct answer is A. It had a little impact. Texas independence came with the defeat of General Santa Anna.
The importance of the treaty was that they established the terms of the end of the war with Mexico. The treaty considered the release of San Anna if he convinced Mexican rulers to accept Texas independence.
But Mexican government did not considered that option because Santa Anna was a prisoner of the U.S. Army, so he had no authority to sign the treaty.
Santa Ana was taken prisoner after being defeated by the U.S. Army in San Jacinto, on April 21, 1836.
