My initial reaction was to like C, then B, then A.
A has got what looks like OB running down the left side. I hate OB left, but that's because of my game, not on any sort of general principle. That green complex is really tight, with OB left and water short and right, and that's what I like least about this hole - I see very little room for recovery around the green, so it just comes across as too penal to me. Since 421 is out of my reach anyways, I'd play short right, then short left, and hope for an up and down or an easy bogey. I like the second bunker left to keep the very long hitters from having too easy a go at this hole. The bunkers look like they've got that ugly blinding white sand in the them, yecch.
On B, the teebox looks like it's oriented just right of the bunker, and straight at the green. I think the intial temptation is to just go for it with a slight fade. Then you're looking at having to carry a bunker with a short to mid iron. Going left is great for the ground game, and you'll need it with a mid-to-long iron. I don't really find it all that compelling. I'd much rather play right and have a short iron over the bunkers. In fact, I don't think I'd even think about it. Now, if the green slopes front right to back left, making that short iron iffy to hold, then we're talking.
From just the aerial photos, I like C the best. I think it would be the most unnerving hole. The tee boxes are aimed at the water. The temptation is to bail right, but that sets up a dangerous approach to the green. I'd rather come in from the left side of the fairway, and while I've got water to carry at least I'm also hitting away from it. Plus, the fairway bunker is the most in play for most players, being closest to the tee box. I don't know, it just seems the juiciest hole. There are just so many opportunities for success and disaster!
I'm going to guess Robert Trent Jones did A. I have no clue as to C.
