They are all wrong!
One way of saying what you wish to say would be:
I want to know which of these cities is the biggest: London, Paris, New York.
When more than two things are being compared, use the superlative, not the comparative.

I bungled that one up pretty badly, didn't I? You are quite right, and I 'll have to reformulate my original question which was about another aspect of grammar altogether. My apologies.
Which of the following are correct:
1-I want to know which of the cities London, Paris or New York is the biggest.
2-I want to know which of the three cities London, Paris or New York is the biggest.
3-I want to know which of three cities, London, Paris or New York, is the biggest.
4-I want to know which of these cities is the biggest: London, Paris or New York.
5-I want to know which of the cities of London, Paris or New york is the biggest.
Right. They are all fine, except 3 and 5. I’d say that 4 is the best.
