TPO9 conversation2 - 英檢

請問一下TPO9的conversation2的一個題目:
4. How does the man probably feel at the end of the conversation?
a)Annoyed that he has to pay a fine on the book
b)Upset that he will lose his library privileges
c)Glad that he can keep the book for two more weeks
d)Appreciative that the woman is helping him
而這段原文是：
L: But, before you go, what you should do is fill out a form requesting
the book back in two weeks. You don't want to waste any time getting it back.
S: Thanks a lot.
Now I don't feel quite so bad about having to return the book.

我的問題是,為什麼答案是Ｄ而Ｃ是不行的？
學生回答說:因為沒有很差的feel必須要還書
我的理解是=>因為多了兩個星期,所以feel還不賴

我知道Ｄ也沒問題,只是好奇Ｃ為什麼一定是錯？
