Concept:Caliban, freed from his foolish loyalty to Stephano, resolves to change his conduct so that Prospero will grant him pardon.
Explanation:In these lines, Caliban agrees to carry away the luggage as he has been commanded to do.
His deeper promise, however, lies in his words that he will “be wise hereafter” and “seek for grace.”
To be “wise hereafter” means that he will no longer be misled by the drunken servant Stephano.
To “seek for grace” means that he will look for mercy and forgiveness, especially from Prospero.
He calls himself a “thrice-double ass” because he mistook a drunkard for a god and bowed down to him.
He now realises his mistake and blames his own folly rather than accusing his companions.
Therefore, his pledge is not merely to carry loads or to reveal the conspiracy.
He is promising to live sensibly and behave properly so that he may earn forgiveness.
Answer:Behave appropriately for forgiveness (Option B).
