Answer: d. the Mariner's guilty conscience
Explanation: In "The Rime of the Ancient Mariner" by Samuel Coleridge, the men's gazes, which result upon the Mariner even after they die, symbolizes the Mariner's guilty conscience. The Ancient Mariner sees the ghost ship and realizes it's Death and Life-in-Death who are gambling for the Ancient Mariner's soul. Life-in-Death wins and he is the only one to survive. The men die cursing the Ancient Mariner with their eyes which keep looking at him after they die. This represents the guilt that he feels for having killed the Albatros.
