Answer to Question 1

E

Answer to Question 2

There has been a large amount of surface activity that has obliterated the craters from much of Triton's surface. These are fissures, nitrogen geysers, and large frozen water ice lakes that are indicative of this activity. This probably is generated by the tidal stresses of its retrograde orbit close to Neptune.
