【答案解析】[听力原文] 11-13
M: Excuse me, are you waiting to buy the concert tickets?
W: Yes, I am. So are all these people in front of me.
M: How long have you been here?
W: About 50 minutes. I've hardly moved forward in that time.
M: Are you kidding?
W: Not at all. There was a couple up ahead of me who got so fed up that they finally gave up and left. They said they'd been here for more than an hour.
M: My God. Does anyone know what's causing the delay?
W: It could be that there aren't enough people selling tickets this afternoon. Or maybe their computers break down.
M: I just hope they don't run out of tickets when I get up there.
W: That really would be annoying, wouldn't it?
M: I guess I should have come before lunch. Or has it been like this all day?
W: Actually it has. In fact, before I came, I tried calling to order my tickets over the phone, just to avoid this long wait, but they don't take phone orders, or checks, or credit cards. It's cash or nothing. And you have to come in person.
M: Well, there are two more hours before the ticket office closes. Tickets to a good concert are worth waiting for. So I think i'll just make myself comfortable.
由对话中女士所说“It could be that there aren't enough people selling tickets this afternoon,"可知，对话发生在下午，结合对话最后男士所说“there are two more hours before the ticket office closes.”，可以判断出对话发生在下午三点左右，因此选项[C]正确。
