A. that depends
B. I can’t tell you
C. there is some doubt
D. you really have me there

A. that dependsB. I can’t tell youC. there is some doubt(答案→)D. you really have me there解析：句意:--你知道为什么在地平线上的太阳看起来更大吗？--嗯，你可把我难住了，我从来没有看过关于此类问题的东西。that depends 看情况吧；I can’t tell you我不能告诉你；there is some doubt能否排除这个可能性；you really have me there你可把我难住了。have somebody的意思是：击败某人，胜过某人，或者是难住某人。根据句意故选D。

和我的回答一样，看来我也对了
