The right answer is the C: Adam has a peace in leaving Eden because of things he has learned. This is part of a dialogue between Adam and the Archangel Michael. The Archangel has been telling him about what the future will bring (" [...] and thence shall come, when this world's dissolution shall be ripe, with glory and power to judge [...] so shall the world go on, to good malignant, to bad men benign [...] " and so on), and he replies by saying "How soon hath thy prediction [...] Beyond is all abyss, Eternity, whose end no eye can reach.
