A
The lobate lava flows spreading out from a common location as seen in A show Io is still volcanically active.
PHOTO - This set of photographs shows various landscapes on Io and Europa. Which image shows that the surface of Europa has been tectonically deformed?
D
In image D we see large, criss-crossing fractures that are evidence of extensional tectonics.
