请教 大全987-73

请教大家了

73        Alaska regularly deposits some of its profits from the sale of oil into a special fund, with the intention to sustain the state’s economy after the exhaustion of its oil reserves.

(A) fund, with the intention to sustain the state’s economy after the exhaustion of its oil reserves

(B) fund, the intention of which is to sustain the state’s economy after they have exhausted their oil reserves

(C) fund intended to sustain the state’s economy after oil reserves are exhausted

(D) fund intended to sustain the state’s economy after exhausting its oil reserves

(E) fund that they intend to sustain the state’s economy after oil reserves are exhausted

大全的答案是C

我觉得A好像更好些，因为C是intended to sustain the state’s economy after oil reserves are exhausted好像是过去分词在修饰前面整个句子，同位结构应该要好些吧？但A的结构又显得有点不简洁

不知道大家是怎么分析的？
