The account of the Tower of Babel is found in Genesis 11:1-9. At that time, all people on earth spoke a single language. They settled in the plain of Shinar and decided to build a city with a tower that reached to the heavens, saying, "Let us make a name for ourselves, lest we be scattered over the face of the whole earth."
God observed their ambition and said, "If as one people speaking the same language they have begun to do this, then nothing they plan to do will be impossible for them." In response, God confused their language ("confounded their tongues") so that they could no longer understand one another. Unable to communicate effectively, the builders abandoned the project and were scattered across the earth.
The name "Babel" is linked to the Hebrew word balal, meaning "to confuse," reflecting the confusion of languages. The other options describe divine judgments from different biblical events: the flood is from the Noah narrative (Genesis 6-9), scattering by war is not from this account, and fire consuming people recalls Sodom and Gomorrah (Genesis 19) or Elijah on Mount Carmel (1 Kings 18). The specific judgment at Babel was linguistic confusion, not physical destruction.
