Answer: D) If I give in to this foolish journey, I will be wasting my time.
Step-by-step explanation: In the given lines from Dante's work, we can see that he is doubting whether or not he should go in the journey the muses have chosen him for. He doubts of himself, of his capabilities and he isn't sure about he being worth of being chosen. After all the doubts and asking the muses why they chose him, he gives in and decides to not go on.
