You do realize that option 1 prevents the players from having information that they should be aware of, right? The creature reeks of blood and carrion, which PCs would instantly know and should therefore be described to the players BEFORE the players start inquiring further about the creature in question.
You are more concerned with the timing than I am. I am fine with a game where the players ask ‘does it have s discernible odor’ and the GM then mentioning the blood and carrion.
