Which work features a character named Ishmael and a great white whale?

The work that features the character named Ishmael alongside the great white whale is "Moby-Dick" by Herman Melville. Ishmael is the narrator of the story, and his journey aboard the whaling ship Pequod is central to the novel's exploration of obsession, revenge, and humanity's relationship with nature. The great white whale, Moby Dick, serves as both the physical antagonist and a profound symbol of the unknown and the uncontrollable forces of nature that the characters, particularly Captain Ahab, grapple with throughout the narrative. This complex interplay between Ishmael and Moby Dick forms the essence of the story, making "Moby-Dick" a cornerstone of American literature. The other options, while featuring notable characters and themes, do not include both Ishmael and the great white whale.
