have you ever been to Rome?--no,but that's the city ___

have you ever been to Rome?--no,but that's the city _ b __
a where i most like to visit
b i'd most like to visit
c which i like to visit most
d where i'd most like to visit
这是个定语从句.
the city 是先行词,它在后面的从句中作宾语,本来用关系代词which 或that.但是因为先行词作宾语,所以关系代词省略了,因此选b .the city是visit 的宾语,属于动宾.

c which指代the city

C
