A.2005 and then to stabilize at six billion cubic feet a day, which will allowsuch an extraction rate at least for

B. 2005 and then tostabilize at six billion cubic feet a day, an extraction rate that will allowat least

D.2005, then stabilizing at six billion cubic feet a day, allowing such anextraction rate for at least

E.2005, then stabilizing at six billion cubic feet a day, which will allow suchan extraction rate for at least

NN们，其他错误都知道，就是A中不考虑which的错误，这里for是错的还是对的呢？

hey,最后一句话我们改写成正常语序就是an extraction rate that will allow at least 50 years' production.
这里allow的意思是：provide sth or set sth aside for a purpose or in estimating sth （为某目的或作估计）留出, 打出某事物: 做这个意思讲时allow的idiom就是allow sth. (for sb.)
