When mexico won its independence from spain in 1821, texas was a spanish colony. owned by the united states. an independent nation. a province of mexico.

The correct answer is - a province of Mexico.

In the period when Mexico gained its independence from Spain, Texas was still part of Mexico and it was one of its provinces. This change soon after though when the United States managed to win over the Texas territory from Mexico and incorporate it into their own territory. Even though Mexico has been trying its best to keep Texas or win it back, it did not had the Spanish support anymore and the United States were much stronger military force so they had to accept the fact that it is a territory that is lost forever.
