Answer:
A) If Gregor had only been able to speak to his sister and thank her for everything that she had to do for him, he would have tolerated her service more easily. As it was, he suffered under it.
Step-by-step explanation:
The keywords in the question are "pain" and "alienation". Answer choices B and C do not have to do with pain, and have a generally neutral connotation. Answer choice D is negative, but it's speaking about apples thrown at Gregor, and is not related to alienation.
Excellent. Answer choice A must be the correct option. This is supported by the phrase "If Gregor had only been able to speak to his sister" which references alienation, and the word "suffered" which links to pain.
Hope this helps!
