In the beginning there were various groups of them: ragged little bands that roamed the forest on foot or horseback . . .
Ice clung to their eyebrows and beards and eyelashes, and I’d hear them whining and groaning as they walked.
In time I began to be more amused than revolted by what they threatened. It didn’t matter to me what they did to each other.
Spears flying, swords whonking, arrows raining from the windows and doors of the meadhall and the edge of the woods.
In time, I began to be more amused than revolted by what they threatened. It didn’t matter to me what they did to each other, is the line best helps the reader understand Grendel’s character. Hence, option C is correct.
What is the concept of the passage?
It gives us an alternative viewpoint of Grendel from his own perspective. We can tell that he initially detested people and envied them, which is why he repeatedly assaulted them. Over time, though, he began to find them to be amusing little things, but he continued to kill them this time for amusement.
The term "ragged small bands that patrolled the forest on foot" illustrates and conveys how intelligent killers we humans are. We kill living things strategically, and that is the frightening aspect of us. Consonance is the literary device that is employed.
Thus, option C is correct.
