Question

how does the tectonic activity of the terrestrial planets compare with that of the gas giants?
all of the terrestrial planets exhibit or have exhibited tectonic activity, but none of the gas giants have.
all of the gas giants experience tectonic activity, but none of the terrestrial planets do.
all of the gas giants experience tectonic activity, but only one terrestrial planet has tectonic plates.
all of the terrestrial planets exhibit or have exhibited tectonic activity, but only one gas giant has.

Explanation:

Terrestrial planets (Mercury, Venus, Earth, Mars) have solid rocky - surfaces which can support tectonic activity like plate movement, volcanic activity etc. Gas giants (Jupiter, Saturn, Uranus, Neptune) are composed mainly of hydrogen, helium and other gases with no solid surface in the traditional sense for tectonic activity to occur in the same way as on terrestrial planets.

Answer:

All of the terrestrial planets exhibit or have exhibited tectonic activity, but none of the gas giants have.
