Advice best routing from Dubai to Chicago?

I am planning to travel from Dubai (Middle East) to Chicago (IL, USA). Can anyone suggest what is the best routing to take. I came across 3 options:





(a) Travel Dubai-London and take another flight London-Chicago.





(b) Travel Dubai-Washington, and then domestic flight to chicago.





(c) Travel Dubai-NewYork and then domestic flight to chicago.





Could anyone suggest what is best and why? Thanks in advance.Advice best routing from Dubai to Chicago?
