【正确答案】 C

【答案解析】[听力原文]
   M: Ella? This is Dan. Listen, I'm still at the office and I'm going to be delayed getting to the presentation. My computer just crashed with all my presentation slides.
   W: How late will you be? Mr. Armstrong arrived at the factory five minutes ago, and you know he doesn't like to be kept waiting.
   M: I know! We're trying to transfer the files to a new computer, but it will probably take another twenty or thirty minutes before I can get there. Can you have someone present before me?
   W: You're the only presenter for today, Dan. Look, you'd better just get over here and make the presentation without the slides. I'm sure Mr. Armstrong will understand.
选项A错误，Dan的话表明他将要去开会。选项B错误，其他人正在工厂等待。选项C正确，Dan一开始就说自己还在办公室。选项D错误，由对话得知，Dan的电脑坏了。
