Đáp án D.

Nghĩa câu gốc: Chúng tối đến sân bay. Chúng tôi nhận thấy hộ chiếu của chúng tôi vẫn ở nhà.

Cấu trúc câu: Not until S + V + auxiliary + S + V (inf).

Đáp án A sai cấu trúc: It was NOT until…that S + V.

Đáp án B sai thì “…our passports are still at home”.

Đáp án C sai cấu trúc, đảo ngữ với “not unti;” chỉ thực hiện ở vế sau.
