The correct answer is A) because of their burning passion for liberty.
The other options of the question were B) because of the Alamo's original use. C) because what Santa Ana did to their bodies. D) because what the ghost did to the Alamo.
The best possible explanation for why the first ghosts seen were flaming spirits with their bodies on fire because of their burning passion for liberty.
That should be a metaphoric interpretation of the first ghost seen in the Alamo when the Mexican troops of Santa Ana tried to destroy the place. Tradition says that when the Mexican troops approached the church of The Alamo, six "fully formed flaming ghosts" appeared and ordered the troops to stop and go away. Even today, people have reported sightings in the Alamo, a building that originally was built as a church for the San Antonio de Valero mission, in 1718.
