The <em>line of dialogue</em> expressing the soldiers' actions is <em>C. "I'm afraid of Grendel."</em>
The soldiers recalled the unsavory experiences of their colleagues in the hands of Grendel. Grendel was the monster that had terrorized the Danes and murdered many of the soldiers.
For Beowulf to engage them to help fight Grendel in "a kill or die" fight, their only actions would be marked by their fear of Grendel. This fear is so palpable that it was oozing out from their pores, from head to toe.
Luckily, Beowulf was able to conquer the archenemy of the Danes in the presence of the soldiers. He went ahead to kill Grendel's mother, ending the Danes' horrendous ordeal.
