After Gregor Samsa turns into an insect in Franz Kafka’s The Metamorphosis, his concern for his family members remains intact. Which of these excerpts best shows that Gregor is worried about his family?

The chief clerk had to be held back, calmed down, convinced and finally won over; the future of Gregor and his family depended on it! If only his sister were here! She was clever; she was already in tears while Gregor was still lying peacefully on his back. And the chief clerk was a lover of women, surely she could persuade him; she would close the front door in the entrance hall and talk him out of his shocked state. But his sister was not there, Gregor would have to do the job himself.

“I was quite alright last night, my parents know about it, perhaps better than me, I had a small symptom of it last night already. They must have noticed it. I don't know why I didn't let you know at work! But you always think you can get over an illness without staying at home.”

He spent the whole night there. Some of the time he passed in a light sleep, although he frequently woke from it in alarm because of his hunger, and some of the time was spent in worries and vague hopes which, however, always led to the same conclusion: for the time being he must remain calm, he must show patience and the greatest consideration so that his family could bear the unpleasantness that he, in his present condition, was forced to impose on them.

Whatever was said next would be crucial, so, in order to make his voice as clear as possible, he coughed a little, but taking care to do this not too loudly as even this might well sound different from the way that a human coughs and he was no longer sure he could judge this for himself. Meanwhile, it had become very quiet in the next room. Perhaps his parents were sat at the table whispering with the chief clerk, or perhaps they were all pressed against the door and listening.
