This may be a trick question, with the answer being there are no such things as fire breathing dragons.
Anywho, I had the same idea as you with the dragon door. But whether you wallk through a door or not you're still exposed to the sun or dragon. It should be more clear if the man walks through or not... and if you're exposed to harm before walking through, or only after walking in through the door.
edit: Looked at it again, and you can only be harmed after walking in through the door. There's the possibility of avoiding a dragon, but you wouldn't be able to avoid heat from the sun, so your chance of survival is much better with the dragon.
It's either that or both are 100% deadly, so choosing the sun makes more sense... instant death instead of moments of suffering.
However...
If you
don't walk through, then you should choose the sun... because a dragon could walk through to
your side.
