The range of distances from a star where water can exist as a liquid.
The correct answer is the range of distances from a star where water can exist as a liquid. This zone is defined by temperature. If a planet is too close to its star, it will be too hot and water will boil away. If it's too far, it will be too cold and water will freeze. The habitable zone is the 'just right' region in between.
The other options describe other planetary characteristics that are not the definition of the habitable zone.
