The correct statement regarding the tectonic activity of terrestrial planets compared to gas giants is:
All of the terrestrial planets have exhibited tectonic activity, but none of the gas giants have.
Terrestrial planets like Earth, Mars, Venus, and Mercury have experienced tectonic processes, including plate tectonics and volcanic activity. In contrast, gas giants such as Jupiter, Saturn, Uranus, and Neptune do not have solid surfaces in the same way and do not exhibit tectonic activity akin to that observed on terrestrial planets.
