The next question_was put to meby Mary.A.i found difficult an answer B.i found it difficult to answer C.that i found it difficult to answer D.i found difficult to answer it
同意一楼的观点。A应该是(that)I found difficult to answer。that I found difficult to answer 定语从句,修饰question。因为that在定语从句中作宾语,所以可以省略。 如果把定语从句单独拿出来作为一个句子,就是I found the question difficult to answer
