The correct answer is B. Mars does not show evidence of plate tectonics.
Step-by-step explanation:
Volcanoes occur as gases, lava and other materials that are under the crust of a planet, escape to the surface as the tectonic plates that form the crust move or collide, which causes the crust to break. In the case of Mars, scientists have found there are no tectonic plates, and due to this, lava, gases, etc. can escape to the surface more easily than on Earth or other planets with tectonic plates. This explains why on Mars there are many volcanoes, and many of these are larger than regular volcanoes found in other planets including Earth. Thus, Mars has one of the largest volcanoes in the solar system because "Mars does not show evidence of plate tectonics".
