Hello.
I would hate to reply with bad info.
I will only give you what I think.
It seems to me that if your application was not processed, it should be very similar to a withdrawn application. So you were not rejected.
Do you know, by any chance, why was your application not processed in that case?, maybe full quota?, or was it incomplete?
Anyway, if I was you I would select NO to the question and complete the profile. And, I would call them tomorrow first thing to make sure it is OK. If it is not, then you change it, if it is, you have your profile ready for the draw.
Hope to be of help. But please, know that this is only my opinion. It is by no means an expert's advice. I don't know much about the process before the EE.
