Answer to Question 1

C

Answer to Question 2

Triton's orbit around Neptune is retrograde (opposite to the planet's rotation) and highly inclined. It is a large, round satellite with an apparently active geology. Its large size and round shape suggests it formed from the accretion of large numbers of planetesimals, yet its orbit argues that it did not form in situ around Neptune as the planet condensed from the protosolar nebula. It appears to have formed in the outer regions of the solar system, perhaps in the Kuiper belt like Pluto, and was subsequently captured.
