Answer to Question 1

C

Answer to Question 2

Perhaps the high temperature of the Venusian surface prevents the formation of rigid plates like on Earth. Maybe our hydrosphere is a critical lubricant for plate motions. Maybe the crust is thinner, so it is easier for lava to erupt as volcanoes like the coronae and prevent the convective cycle that causes plate movement.
