【正确答案】 D

【答案解析】根据句意和句子结构，我们可以看出宾语从句的谓语动词decide发生在主句谓语动词said之前，因此，从句谓语动词只能使用过去完成时，例如：He said that they hadpaid him a visit two days previous to the National Day．他说他们在国庆节前两天拜访了他。He said he had forgotten to tell it to her and further，he didn’t want to tell her．他说他忘了把那件事告诉她了，而且他也不想告诉她了。I am gratified that they appreciated what I haddone for them．我很满意，因为他们很感激我为他们做的事。
