Redirect to a specific branch depending on how many answer I got to a multiple selection question

Hello Folks,

I have a question where I ask my users to select up to 3 cities where they are interested to invest on. 
After submitting the form, I want to redirect them to a booking form based on their answer, but the tricky part is that it will also depend on how many answers they gave.
Example: if they only answer Paris, I will redirect them directly to the booking page of my Parisian expert but if they answer several cities at once, I will send them to a global sale that will help them narrow their destination. 
Currently if I set a condition like if 5 = Paris then go to B if the redirection happens if any of the answer is Paris, not if the exact answer is paris.

Any idea on how I could achieve this ?
