D.was to blame 为正确选项。首先：sb be to blame 是固定搭配，“。。。是某人的错”“。。。某人的责任”的意思。如I am to blame.（是我的错）。其次，句子的主语是he，而不是 Alice and Lira，它们只是插入语，故谓语动词用was而不是were。其实，原句即为：Mr Sam thought he himself（ was to blame ）for the coldness that had grown between them rather than Alice and Lira。解答完毕。个人体会：理清句子结构和熟悉各种固定搭配是解答本题的关键。
