I was blown away by the fold until I noticed you had a 4 flush. Even with the 4 flush, I think this is a pretty easy call. You're getting the odds to draw, especially when you consider that you'll often make several bets on the river when you hit 2/3 of your outs.

Also, A is going to call here the vast majority of the time. He reraised before the first draw with a two card draw and bet when he made his one card draw. He has a decent hand (or he is a terrible player who is still likely to call).
