Đáp án B

B. He cannot have known that his brother graduated with very high marks: cách dùng động từ khiếm khuyết “cannot have + Vp.p” để diễn tả một sự suy đoán về một sự việc đã xảy ra: “chắc là đã không làm điều gì”.

Cách dùng này hợp ý nghĩa với câu cho sẵn: “Tôi chắc rằng anh ấy không biết là anh trai của anh ta đã tốt nghiệp với hạng danh dự”.
