Answer:
The correct answer is option C. "This mirrors how Grendel gradually develops understanding".
Explanation:
In the novel "Grendel" by John Gardner, the antagonist of "Beowulf" gets his own story under his point of view. In this novel the story starts with the monster Grendel being in an unlit cave. This mirrors the narrow vision that Grendel has when the story starts, which gradually develops as the events of the novel take place. Right from the beginning, Grendel's encounter with his mute mother that ventures him to leave his cave was the first event that started to develope his understanding.
