PLO 5/10 ... 2pr + Nut Flush Draw facing re-raise and call.

[Bartholow]

Without looking at other responses, I think I'd just call. The raise and cold call show a lot of strength; I think you are probably behind here but you're getting like 3.5-1 to hit your flush draw with probably some implied odds with two other players in there. And while I wouldn't put in a ton of action with an A, you could win that way too maybe.
