URGENT - Who is paying for your trip? (H1B)

I need answer urgently. I am filling the DS 160 and there is a question - Who is paying for your trip? Should I choose Self or US Petitioner?

As of now I do not have any money from my US Petitioner for flight tickets and any proof that they will be paying for my tickets.

Generally, the answer is self. The question relates more to finding out where your tickets are originating and if it is violating any anti-terrorism laws rather than finding out if you can afford the tickets as is commonly believed. Either way the answer is self. Best wishes
