The correct answer is - A) Texas is the second largest state in the United States.
The fact that Texas is the second largest country in the United States, after Alaska, doesn't have anything to do with its culture. The state can be very small, or very big, and still have either big diversification, foreign influence, or be homogeneous in cultural aspect.
Texas is as it is because it has both, Latin American and American influence, and that is what it's making it beautiful and unique in its own way.
