D
意思是：丽莎现在不可能在家,我刚刚到机场去接她.
表推测,表示“不可能”时,必须用“can't"

B
丽萨现在一定不在家，我刚看到她离开机场

D can't 表不可能

D
丽莎现在不可能在家，我刚在机场送她。
首先，通过后面那句话推断出她不在家，排除掉A,C
然后，mustn't的意思是不可以，排除
can't be 的意思是不可能。所以选D

D.can't
Lisa 现在不可能在家,我刚在机场为她送行.
can't be at home意思是不可能在家,固定用法,死记并且活用就OK了.

D
cant' do除了有不能做某事的意思，还可以表示对现在事情进行否定的推测，
lisa现在一定不在家。我刚刚在机场为她送行。

应该选D。
依题意，Lisa现在肯定不在机场。
must做“必定”意思时否定形式是Can't。
must‘T是need的否定形式
翻译：Lisa一定不在家，我刚到机场送完她

D 表否定推测用can't 表肯定推测用must
