Alex changed his mind at the last minute，otherwise we ________ an agreement.

A．should have reached B．could have reached
C．can reach D．should reach

B

解析句意為：亞歷克斯最終改變了主意，否則的話我們就會達(dá)成一致了。對過去事情的推測，應(yīng)該使用“情態(tài)動詞＋have done”。should have done應(yīng)該已經(jīng)做了……；could have done很可能已經(jīng)做了……。所以應(yīng)該選擇B項。
