To gain their freedom on the Underground Railroad, escaping enslaved people would typically need to cross the Rio Grande if they were heading to freedom in territories like Mexico. The other rivers mentioned (the Brazos, Colorado, and Red Rivers) are located in Texas but are not directly associated with crossing for freedom in the context of the Underground Railroad. Therefore, the best answer is the Rio Grande.
