嗨！压力太大，还整错了一个~~

5: Which of the following is NOT a suitable final sentence for a formal letter?
The possible answers were:
I look forward to hearing from you soon.
Hope to see you soon.
Looking forward to a swift response.
Looking forward to meeting you.


-------------------------------------------------------
Looking forward to meeting you.
“期待着与你会面”是个正式的结束语。


Not a formal one,
俺咋较的是 Hope to see you soon.

Or the question should have "not" removed to make sense, since "Looking forward to meeting you" is the only proper expression here.
