Which of the following passages from the story best shows Kafka's use of tension?

A. However, his sister noticed the full dish immediately and looked at it and the few drops of milk splashed around it with some surprise. She immediately picked it up — using a rag, not her bare hands — and carried it out.
B. If Gregor had only been able to speak to his sister and thank her for all that she had to do for him it would have been easier for him to bear it . . .
C. I'd have gone up to the boss and told him just what I think, tell him everything I would, let him know just what I feel.
D. It was not until it was getting dark that evening that Gregor awoke from his deep and coma-like sleep. He would have woken soon afterwards anyway even if he hadn't been disturbed, as he had had enough sleep and felt fully rested.
