一道题不明白，求高人指点一下

Japan received huge sums of capital from the United States after the Second World War, using it to help build a modern industrial system.

(A) Japan received huge sums of capital from the United States after the Second World War, using it to help build
(B) Japan received huge sums of capital from the United States after the Second World War and used it to help in building
(C) Japan used the huge sums of capital it received from the United States after the Second World War to help build
(D) Japan's huge sums of capital received from the United States after the Second World War were used to help it in building
(E) Receiving huge sums of capital from the United States after the Second World War, Japan used it to help build

答案选C，但是我有一点不明白，在原句中，using是个分词的形式，是个伴随动作，如果选C，use变成了主句的谓语，这样不是改变了句子表达的重心吗，当然别的答案也都有问题我承认。

其实改变句子重心一说并不完全正确。因为原句是划线的，所以原句的意思可能本来就会错。其实相比其他选项而言，只要句义合理都是可以的，千万不要拿改变重心去排除选项，这不是绝对错误
