The question below is from my English exercise book.
Select the most suitable response to fill in the blank.
"Excuse me, which is the way to the post office?"
"Sorry, I'm new here. _______"
A. Not at all
B. Bad luck
C. That's true
D. Thank you all the same
For me, all four choices seem to be quite weird. However, I choose option B (Bad luck) because I feel it is the least weird reply in this conversation.
Is my understanding correct? Or should I contact the book's author to change the question and options?
P/S: After seeing Andrew and choster's comments, I have searched the original question on the Internet and it should be like this:
[Speaker A:] "Excuse me, which is the way to the post office?"
[Speaker B:] "Sorry, I'm new here."
[Speaker A:] "_______"
