Most stars have one or more terrestrial planets orbiting within their habitable zones is the correct answer.

Explanation:

According to the science, the habitable zones are the region around the stars where one or more terrestrial planets can orbit. A terrestrial planet orbits inhabitable zone is called potentially habitable zone which have roughly comparable conditions to those of earth.

This situation is a proof stating that most of the stars have one or more terrestrial planets orbiting within their habitable zone.
