AQ facing 3bet

[Hosehound25]

Villain is 21/17/5.5 (150). I'm running at 17/13 overall, but may of been opening the pot a little bit more frequently at this table. I have also been 3bet PF 2 or 3 times and folded each time. Just want to know what you think of each option here, 4betting, folding, or calling. I thought folding>4betting>calling. What do you think?
