gwd-24-38 不明白

24-38 In January 1994 an oil barge ran aground off the coast of San Juan, Puerto Rico, leaking its cargo of 750000 gallons into the ocean, while causing the pollution of the city’s beaches.

A) leaking its cargo of 750000 gallons into the ocean, while causing the pollution of

B) with its cargo of its cargo of 750000 gallons leaking into the ocean, and it polluted

C) and its cargo of its cargo of 750000 gallons leaked into the ocean, polluting

D) while it leaked its cargo of 750000 gallons into the ocean and caused the pollution of

E) so that its cargo of 750000 gallons leaked into the ocean, and they were polluting

首先，可以认为C中的its cargo of its cargo of 是打错了，ETS应该不会用这种表达来折磨我们。我的问题是，如果C是答案，句子结构是：a barge ran around……, and its cargo leaked……，polluting……。为什么，its cargo 后的leak不用被动，我觉得应该是its cargo was leaked吧 cargo能主动就leak了么？

船上的货物泄漏了,为什么要说被泄漏了呢??????
