What animal can win in a match: a crocodile, a lion, or a cobra?

The snake, if it was a King Cobra. It is the only animal that purportedly can kill a healthy adult elephant. I would bet on the snake, but it would also die due to the mauling it would take before the alligator or lion sucbed to it's poison. Other snakes have more potent venom, but at 15 feet long the cobra would have mive amounts of venom and fangs long enough to all skins.
