W: When did you leave for Beijing last Sunday?
M: Oh, I planned to take the 8:50 train. But the manager phoned me at about 8:15 and asked me to deal with something urgent. When I finished it, it was already 9:50.
W: So you had to take the 10:30 train. Right?
M: Yes. But when I hurried to the railway station, I was told the train would be delayed for fifteen minutes.
解析：
正确答案为C。对话中提到，男子准备乘10：30的火车，但是火车晚点了15分钟，可知男子离开北京的时间应为10：45，因此C正确。
