Why 'I'd Most Like to Visit' is the Correct Answer

I've never been to London, but that's the city I'd most like to visit. Why is 'I'd most like to visit' the correct answer? This is because the sentence is expressing a desire or preference to visit London. The alternative option, 'where I like to visit', suggests that the speaker frequently visits London, which is not stated in the sentence. The phrase 'I'd most like to visit' clearly indicates a preference for London as a travel destination.
