-How do you like the cake?-It’s quite different frome__I had

-How do you like the cake?-It's quite different frome__I had last month
A.that
B.which
C.the one
D.the one what
why we choose

此句用的基本短语是A is different from B
在句中A 是It . B是 _____ i had last month
如果选A 的话,没有先行词.应该是the one that 或the cake that
B和A 错的是一样的,没有先行词.
C.为什么可以呢,本来最完整的答案是：the one which/that 但是,关系代词在定语从句中作宾语的话是可以省略的.在这里,关系词作的是had 的宾语,所以省略了.（had在这里翻译成吃）
D what 不可以作关系代词,要改成that 或which就对了.或者你把the one 却掉也是正确的.what i had last month也是正确的.
