HIs lecture was difficult and I didn't know -------he said meant in his lecture.
A.that B.what C.that that D.what waht
请问为什么选D

的确选D,先看看后面那个what--what he said,这的what指代的是said后面的内容,翻译出即使“他所说的”
前面那个what--what (what he said做这从句中的主语)meant in his lecture,这个what指代的是meant后面的内容,翻译出来是“(他所说的)在他的演讲中意味这的什么”
这个句子的意思是:他的演讲很难,我不知道他所说的在他的演讲中意味的什么.(即指我完全不懂他在说什么)
