Answer:
The answer is C
Step-by-step explanation:
The literal meaning of the following quote "The land thou knowst not, / place of fear, where thou findest out / that sin-flecked being. Seek if thou dare!" is (c) which says go into those unknown lands and find Grendel's mother, if you are brave enough. "The land thou knowst not, / place of fear, this means land that nobody has ever been to. Where thou findest out / that sin-flecked being refers to Grendel's mother and Seek if thou dare refers to if you are brave enough to face the danger of going into the land.
