Xét các đáp án:

A. Although the project faced delays due to unforeseen circumstances, it was completed on time.

(Mặc dù dự án gặp phải sự chậm trễ do những trường hợp bất ngờ, nhưng cuối cùng vẫn hoàn thành đúng thời hạn.)

B. Unless the project faced unforeseen delays, it was not completed within the scheduled time.

=> sai vì ngữ cảnh đề bài cho ở thì quá khứ viết lại câu phải dùng điều kiện loại 3: If/ Unless S6 + had Ved/P2, S2 + would have Ved/ P2.

C. Due to unforeseen circumstances, the project was delayed, however it was completed on time.

=> sai ngữ pháp vì nếu dùng however đứng giữa câu thì phải được ngăn cách bởi dấu “;”

D. Despite the delay was caused by unforeseen circumstances, the project was finished on time.

=> sai vì despite + N/V-ing mà trong câu này sau despite đang là một mệnh đề
