Yes, the correct answer is A. The siege of the Alamo.

To arrive at this answer, you can follow these steps:

Step 1: Understand the question and options.
Read the question carefully and make sure you understand what it's asking. In this case, you're asked to identify the event that led to Congress declaring war against Mexico. Evaluate each option and try to understand its relevance to the question.

Step 2: Research the events.

- The Whitman massacre was a violent attack in 1847 by Native Americans on a mission in what is now Washington state.
- The Thornton affair refers to a skirmish in 1846 between the United States and Mexico along the Rio Grande.
