OG 178。。好像没人问过

OG178:

In the last few years, the number of convicted criminals given community service sentences, which allow the criminals to remain unconfined while they perform specific jobs benefiting the public, have risen dramatically.

(A) sentences, which allow the criminals to remain unconfined while they perform specific jobs benefiting the public, have

(B) sentences, performing specific jobs that benefit the public while being allowed to remain unconfined, have

(C) sentences, performing specific jobs beneficial to the public while they are allowed to remain unconfined, have

(D) sentences which allow them to remain unconfined in their performing of specific jobs beneficial to the public has（E）

(E) sentences allowing them to remain unconfined while performing specific jobs that benefit the public has

大家看这个从句：allowing them to remain unconfined while performing specific jobs

如果写完整了就是sentences allow them to remain unconfined while performing specific jobs....这里的perform specific jobs的主语明显和前面不一致。可以这样吗？

OG上说D不对，因为wordy和imprecise.

可我觉得D比E准确。大家觉得呢？

今天我也问了这个问题
