帮解一道省略句 i am planning to···
Will you going to the meeting tomorrow
No ,I’m going to see a friend ,or at least I am planning_____
A it B to C that D so
选B 为什么呢?It 和that 不能指代前面谈的那件事吗?So不是用来肯定重复前面说的吗?
很不明啊

plan to do sth.
这里plan to后面省略了 see a friend
补充完整原句应该是
I’m going to see a friend ,or at least I am planning to see a friend.
