Answer:
D, The Mariner has learned to love creatures besides humans.
Step-by-step explanation:
In Samuel Taylor Coleridge’s “The Rime of the Ancient Mariner,” the dead Albatross symbolizes the Mariner's guilt, burden and sin. In that matter, the Mariner gives thanks for the beauty of the water snakes, and finds spiritual renovation. This serves as a symbol of his forgiveness, because the mariner feels reconnected with nature and regrets his sins.
