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

The answer here is C. My question is why can't it be A? The ing modifier modifies the clause before the comma and the use of it would thus rightly reflect the huge sums of capital. If we pick C, wouldn't the sentence imply that the money that Japan received from the United States was for building a modern industrial system? Please help..
