Locks are used as a technique to connect large bodies of water with one another or to connect ports with other ports or cities with other cities.

Well, an epic is a long poem, typically one derived from ancient oral tradition, narrating and adventures of a heroic figure (like Hercules, Beowulf) when you think of an epic just try to remember myths and legends. And with that, I do not think D or C are the answer just due to epics aren't making fun of their culture and the pov (point of view) doesn't change during an epic or story for that matter it gets confusing. Also with answer, A, not every epic has an enchantress so I believe B is the correct answer.
