I feel that it would depend on the officer reviewing your file, but the chances of the application being returned are low. I say that because AOR is just a basic completion check, and as long as you didn't leave a question unanswered, even if answered it incorrectly you will still get AOR. Once you get it, you can use the citizenship file number and inform them of the mistake using the webform (Google "IRCC WEBFORM" for a link). Good luck
