Đáp án B.

Tạm dịch: Cô ấy đi ngang qua tôi trên đường phố mà không nói câu gì. Cô ấy không thể nào là không nhìn thấy tôi.

Can’t + have + PP: trong câu dùng để bày tỏ một sự ngạc nhiên hoặc không tin vào việc cô ấy đi qua trước mặt mình mà lại không nhìn thấy mình, không chào hỏi. Ngoài ra Can’t + have + PP còn dùng để chỉ một sự việc gần như chắc chắn không thể xảy ra. Ex: Last night, Mary can’t have gone out with John because she had to prepare for her coming exam: Tối qua, Mary chắc chắn không thể đi chơi với John được vì cô ấy phải chuẩn bị cho kỳ thi sắp tới.
