B.and, if it would strike Earth, part of the planet could experience a tremendous amount of damage but it would

C.and that, if it were to strike Earth, could do tremendous damage to part of the planet but would

D.and that, if Earth is struck by it, can do part of the planet tremendous damage, but it would

E.and that, if it strikes Earth, it could experience a tremendous amount of damage but
a 也是正确的呀

（Scientists have identified an asteroid, 2000 BF19, that is about half a mile wide ）and, （if it strikes Earth, it can do tremendous damage to part of the planet but probably not cause planetwide destruction.）

两句子并列不对么？用一般时表示虚拟是可以的

首先A是错的，而且错误不只一处

第一个：A中把Scientists have identified an asteroid和 it can do ...并列，不符合原文的逻辑意思，it can do 应该和that引导的从句并列，为了避免歧义，这里需要在and后面补出that

第二个：if 条件句的虚拟语气一定要用过去的某个时态，比如说：if I were you, 这里如果说成if I am you则是完全错误的；因为从句是过去时，所以那个后面的can应该改为could
