单选题 ______ the financial means to remain independent, Thomas Edison was compelled to seek employment as a night telegraph operator.
A. That he was deprived of B. Deprived of
C. He was deprived D. Although he was deprived of

【正确答案】 B
【答案解析】[解析] 非谓语动词用法题。本题谓语动词是was compelled，前半句若是完整句子，应用连词连接两个分句，前后句子是因果关系，而although表让步，故D可排除；A和C在语法上讲不通；B是过去分词作状语，表示原因，符合句意，故为答案。
