I think D best supports the theme of the text.
If this is the passage: "<span>At four hundred miles they stopped to eat, at a thousand miles they pitched their camp. They had traveled for just three days and nights, a six weeks' journey for ordinary men. When the sun was setting, they dug a well, they filled their waterskins with fresh water, Gilgamesh climbed to the mountaintop, he poured out flour as an offering and said, "Mountain, bring me a favorable dream."
Then the answer is: A journey filled with many challenges. At this point of the Epic, Gilgamesh has embarked on a journey to find </span><span>Utnapishtim, the wisest man on earth, to ask him about the eternal life. Such journeys are an indispensable feature of epic poetry. They drive the action forward and provide context for more adventures and occurrences.</span><span>
