Is this the reason _____at the meeting for his carelessness in his work?
A.he explained B.what he explained C.how he explained D.why he explained 我知道这个题选A,若选B这个句子对不对,是否可以看成同位语从句?

此句为定语从句,Is this the reason _____﹙that﹚he explained 省略that
the reason 是先行词,he explained the reason
the reason 做句子宾语,省略that
再问：我想问的是选B这个句子对不对，为什么不能看成同位语从句？
再答：不对, 要是同位语的话, reason 后面的句子应该是他解释的理由,并且后面应不缺成分,显然后面句子缺少成分. 亲,不明白再问!
再问：好吧，有一点点明白，what he explained 缺成分？what当成宾语不行吗？
再答： what he explained has caused some problems. 此句为主语从句,what he explained 作主语.
再问：好吧，虽然知道选A，但不是很清楚，但是我不能再追问了，要不就要浪费财富了。谢谢啊
