Which statements describe Babylon during Nebuchadnezzar's reign?

A. Natural geographic landforms offered protection from invaders.

B. A moat filled with water from the Euphrates River surrounded the city.

The correct answers are B. A moat filled with water from the Euphrates River surrounded the city, and C. Walls around the city provided protection from enemies. This was copied later by many cities beacuse it was successful. Cities would dig deep trenches and holes around the city and fill them with water and you wouldn't be able to enter without crossing the bridge that may or may not be lowered for you.
