Assuming that you're against rewriting the character and/or complete retconning, only the first and third options are really that plausible, and the third option is quite silly unless your intention is to be Zaak Flash, the amazing Null Ra salesman. So if you are hellbent on keeping your character and making the change to Au Ra IC, then having been in Au Ra the whole time and hidden with a glamour would make the most sense, seeing as how glamours exist fairly easily in Eorzea.
